BACKGROUND OF THE INVENTION
The present invention relates to multifunctional water-soluble cross-linked cationic terpolymers and personal care compositions comprising these multifunctional water-soluble cross-linked cationic terpolymers. The present invention also relates to methods for using such cationic terpolymers to treat various substrates; for example, hair, skin, etc.
Cationic polymers have been used extensively in water treatment, paper making, mineral processing, petroleum recovery, textile dyeing, cosmetics and pharmaceuticals. Among the most important and extensively used cationic polymers are the quaternary ammonium polymers of diallyldimethylammonium chloride (DADMAC). These polymers are also known to be used in personal care applications.
Polymerization of DADMAC is typically carried out in aqueous solution using a free radical initiator such as a persulfate salt. Several approaches have been tried to increase the molecular weight of DADMAC polymers, including polymerization with added inorganic salts, polymerization in oil-in-water emulsions or suspended droplets, and addition of cross-linkers during polymerization. These methods are well known to those skilled in the art.
U.S. Pat. No. 3,968,037 discloses that cationic polymers made by inverse emulsion polymerization with cross-linking and branching agents are used as flocculants and for the treatment of activated sewage sludge.
Cationic polymers have been used extensively in home and personal care, water treatment, papermaking, mineral processing, petroleum recovery, fabrics, and pharmaceuticals. Among the most important and extensively used cationic polymers are the quaternary ammonium polymers of diallyldialkyl ammonium compounds. In fact, homopolymers of diallyldimethyl ammonium chloride (DADMAC) are well known in the home and personal care industry as polyquaternium 6, and are used extensively in skin and hair care applications.
The use of homo- and copolymers of diallyldimethylammonium salts in personal care applications has been disclosed in several U.S. patents.
The present invention relates to novel water-soluble, cross-linked, and cationic terpolymers, for example of diallyidimethylammonium chloride (DADMAC) and diallylamine (DAA), that provide excellent conditioning properties. The terpolymers of this present invention provide the extra conditioning benefits required in a personal care product. They also contribute useful properties to skin care products.
U.S. Pat. Nos. 3,700,623 and 3,833,531 teach making certain acid stabilized poly(diallylamine)-epihalohydrin resins, the disclosure of which is herein incorporated by reference. The obtained resin had a tendency to gel on standing. The resin solution was therefore stabilized against gelation by adding enough water-soluble acid (e.g. HCl) to adjust the pH to about 2. The acid-stabilized poly(diallylamine)-epichlorohydrin resins were reactivated prior to use by addition of a base (e.g. NaOH) to adjust pH to above 7. The half-reacted epihalohydrin entities of the alkaline curing resins impart epoxy functionality for crosslinking reactions after being reactivated by addition of alkaline base prior to use. These polymers are insoluble after crosslinking.
U.S. Pat. Nos. 4,354,006, 4,419,498 and 4,419,500 teach a process for making certain poly(DAA-ECH) polymers by reacting a diallylamine (DAA) polymer first with an allyl halide and then with hypohalous acid to convert the allyl substituents to halohydrin moieties, the disclosures of which are herein incorporated by reference.
JP 6,108,382 discloses another way to make certain poly(diallylamine)-epihalohydrin polymers. A diallylamine-epihalohydrin halo salt monomer is first prepared by reacting diallylamine with an epihalohydrin (typically epichlorohydrin, ECH) and then neutralizing with a halo acid (typically HCl).
U.S. Pat. No. 5,147,411 discloses a method to prepare the DM-ECH monomers (3-halo-2-hydroxypropyl)diallylamine and (2,3-epoxypropyl)diallylamine, and their quaternary ammonium salts, the disclosure of which is herein incorporated by reference.
U.S. Pat. No. 4,341,887 discloses that the reaction product of diallylamine and epichlorohydrin (3-chloro-2-hydroxypropyl)diallylamine (a DAA-ECH monomer), can be converted to N,N-diallyl-3-hydroxy-azetidinium chloride (DM-ECH azetidinium monomer) by heating in the presence of water, the disclosure of which is herein incorporated by reference.
The above-reviewed patents involve use of an epihalohydrin as a reactive compound to react with DAA monomer or a DAA polymer. Since an epihalohydrin (e.g. epichlorohydrin) is a difunctional reactive crosslinker, highly crosslinked insoluble end products are obtained when fully reacted with equivalent high DAA-containing (i.e. >5%) polymers.
Commonly assigned U.S. Pat. No. 6,323,306, the disclosure of which is incorporated by reference, discloses a method to prepare certain water-soluble cationic polymers by reacting an amino-functionalized DADMAC polymer with a difunctional reactive crosslinker. The reactive crosslinkers include epihalohydrin and other polyfunctional compounds that can be used to cross-link the diallylamine polymers. The patent is limited to a DAA content of less than 5% to prevent formation of undesirable insoluble products which can be caused by excessive crosslinking due to use of the difunctional reactive crosslinker.
U.S. Pat. Nos. 3,912,808, 3,986,825, and U.S. Pat. No. 4,027,008 disclose DADMAC homopolymers and copolymers with acrylamide derivatives in hair care compositions, the disclosures of which are herein incorporated by reference.
U.S. Pat. Nos. 5,622,647 and 5,476,522 disclose DADMAC and vinyltrialkoxysilane copolymers for dewatering in the mining industry, the disclosures of which are herein incorporated by reference.
Copending U.S. application Ser. No. 11/595,152, filed on Nov. 9, 2006, discloses the preparation of functionalized cationic polymers and their application in personal care, the disclosure of which is herein incorporated by reference.

An amino-group containing base polymer of formula prepared for example as described above, is functionalized or modified by reacting it with at least one reactive functional compound (grafting agent and/or crosslinking agent) (2). Compounds with groups that can react with the amino-functional groups in the base polymer can be used to impart the properties or functionality of the grafting agent used. Suitable reactive compounds for grafting or crosslinking include, but are not limited to, epoxy compounds, haloalkyl compounds, isocyanate compounds and compounds containing activated olefinic double bonds. Suitable reactive compounds for grafting or crosslinking in non-aqueous systems also include acid halides and anhydrides.
In one embodiment of the invention, the functional reactive compound or grafting agent (2) used is an epoxy or halohydrin compound to give the functional group Fg as









which contains a









linkage connecting its residual Fg to the amino nitrogen of the base polymer.
Examples of monofunctional epoxy compounds suitable for grafting include, but are not limited to, the following glycidyl compounds: mono-(2,3-epoxy)propylether-terminated polydimethyl-siloxanes, 3-glycidoxypropyltrimethoxysilane, 1-oxy-2,2,6,6,-tetramethyl-4-glycidyloxypiperidine, glycidyl isopropyl ether, glycidyl isobutyl ether, glycidyl heptyl ether, glycidyl 2-methylphenyl ether, glycidyl hexadecyl ether, glycidyl hexadecafluorononyl ether, glycidyl 4-nonylphenyl ether, 1,2-epoxydodecane, 1,2-epoxyoctadecane, 1,2-epoxy-3-phenoxy propane, glycidyltrimethylammonium chloride, glycidyl 3-nitrobenzenesulfonate, and the like.
Non-limiting examples of polyfunctional epoxy compounds include, but are not limited to, ethylene glycol diglycidyl either (EGDE); diglycidyl ether; 1,2,3,4-diepoxybutane; 1,2,5,6-diepoxyhexane; poly(propylene glycol) diglycidyl ether (PPGDE); 1,4-butanediol diglycidyl ether, 3-bis(glycidyloxy)methyl-1,2-propanediol, bisphenol A diglycidyl ether (BADGE), poly(phenyl glycidyl ether-co-formaldehyde), glycerol propoxylate tri-glycidyl ether, N,N-diglycidyl-4-glycidyloxyaniline, triglycidyl isocyanurate and the like. Preferred epoxy crosslinkers are bisphenol A diglycidyl ether and ethylene glycol diglycidyl ether.
When monofunctional epoxy compounds are reacted with an amine portion of the cationic terpolymer of formula (I), functionalized cationic polymers such as those of the structure (V) can be obtained and wherein the schematic representation below shows only a DAA/DADMAC segment of the cationic terpolymer:









where Fg=H, C 1 to C 30 alkyl or
—O—R










wherein R is hydrogen, C1 to C30 alkyl, C1 to C30 perfluoroalkyl, 1 to 1500 ethoxy units, 1 to 1500 propoxy units, 1 to 1500 mixed ethoxy-propoxy units, j and v are defined previously, and r is a number from 1 to 100.
Certain epoxy compounds in halohydrin form can also be used as reactive compounds for functionalizing the amino cationic base polymer. Examples of these include, but are not limited to, 3-chloro-2-hydroxypropyl-dimethyldodecylammonium chloride and 3-chloro-2-hydroxypropyl-dimethyloctadecylammonium chloride (QUAB® 342 & QUAB® 426 from Degussa). Thus, in the functionalized cationic polymer of formula (V), Fg will be the residue from reacting 3-chloro-2-hydroxypropyl-dimethyldodecylammonium chloride or 3-chloro-2-hydroxypropyl-dimethylocta-decylammonium chloride.
Haloalkyl compounds can also be used as reactive compounds for functionalizing the base amino cationic polymer. Examples of mono-functional haloalkyl compounds suitable for grafting include, but are not limited to, chloroethane, bromoethane, 1-chloropropane, 1-chlorobutane, chloroacetic acid and its salts, dichloride-substituted cyanuric chloride and the like. Preferred haloalkyl reactants are bromoethane and chloroethane because of their low cost. Thus, in the functionalized cationic polymer of formula (Ia and Ib), Fg will be the residue of a haloalkyl compound to give the functional group Fg as









which contains a









linkage connecting its residual Fg to the amine nitrogen of the cationic terpolymer of formula (I).
Examples of dihaloalkyl compounds that can be used to graft or crosslink cationic base polymers containing primary or secondary amino groups include, but are not limited to, 1,2-dichloroethane, 1,2-dibromoethane, 1,3-dichloropropane, 1,4-dichlobutane, 1,6-dichlorohexane, 1,10-dichlorodecane and the like. Preferred dihaloalkyl compounds are 1,2-dibromoethane and 1,2-dichloroethane.
Trihalo compounds such as cyanuric chloride and its chloro-substituted derivatives may also be employed. As is well known, replacement of each halogen on cyanuric chloride is progressively more difficult. This may be exploited to introduce dihalotriazinyl functional groups into a cationic base polymer, with subsequent reaction to introduce further functionality.
Examples of other difunctional reactants to graft or crosslink cationic base polymers include, but are not limited to, N,N′-methylenebisacrylamide (MBA), N,N′-ethylenebisacrylamide, epichlorohydrin, ethylene glycol diacrylate, diethylene glycol diacrylate, poly(ethylene glycol) diacrylate, poly(propylene glycol) diacrylate and the like. MBA is a preferred crosslinking agent.
Depending on the reactant charge ratio, one can preferentially react just one functional group of a difunctional reactant. When used as a crosslinker for the cationic base polymer, only low amounts (0.1 to 3 weight percent) will normally be employed.
Compounds containing activated olefinic double bonds can also be used to graft or crosslink cationic base polymers containing primary or secondary amino groups via a Michael addition. Examples of monofunctional compounds suitable for use in a Michael addition include, but are not limited to, (meth)acrylamide, (meth)acrylonitrile, esters of (meth)acrylic acid such as methyl acrylate, butyl acrylate, lauryl acrylate(LA), 2-hydroxyethyl acrylate (HEA), N-substituted (meth)acrylamides such as N,N-dimethylacrylamide and N-isopropylacrylamide (NIPA). Preferred compounds include 2-hydroxyethyl acrylate, N,N-dimethylacrylamide and N-isopropylacrylamide.
Thus, in the previously mentioned functionalized cationic polymers of formulae (Ia and Ib),









Fg will be the residue from reacting at least one compound containing an activated olefinic double bond, wherein said compound is an acrylate compound, to give the functional group Fg as









which contains a









linkage connecting its residual Fg′ to an amino nitrogen of a cationic base polymer.
When said compound is an acrylamide, it gives the functional groups Fg as









which contains a









linkage connecting its residual Fg groups to an amino nitrogen of a cationic base polymer, wherein the Fg groups are the same or different.
When said compound is acrylonitrile or methacrylonitrile, it gives the functional group Fg as









Anhydride compounds can also graft to base polymers containing primary or secondary amino groups. Examples of suitable anhydride compounds for reactant (II) include, but are not limited to, phthalic, maleic, succinic, pyromellitic and tetrahydrophthalic anhydrides, 2-dodecen-1-yl succinic anhydride and the like. In one embodiment the anhydride compound is 2-dodecen-1-yl succinic anhydride.
The reactive compound is used in an amount ranging from about 0.02 to about 3.0 moles, preferably from 0.2 to 1.0 moles, of functional groups in the reactive compound for each mole of reactive amine present in the base polymer. The equivalent ratio of reactive compound to base polymer may change depending on the desired properties for the final polymer. The reactive compound is used in an amount which is effective to give a product certain desired properties after being fully reacted with the amino functional groups in the base polymer. More than one reactive compound may be reacted, simultaneously or sequentially in any order, with the base polymer.
The grafting reaction can be carried out in an aqueous medium or in the same reaction medium (e.g., water-in-oil emulsion) as is used for preparing the base polymer in step (a). The reaction is preferably carried out in aqueous medium at a pH of from about 7 to about 11, preferably from 7.5 to 9.5, and at a temperature from about 0 to about 100° C., preferably from 20 to 80° C. The solids concentration of the base polymer in the reaction medium prior to reaction can be, by weight, from 1% to about 60%, preferably from 10% to 25% for a solution of the base polymer, and preferably from 20 to 50% for an emulsion or dispersion of the base polymer.
The preparation of the cationic terpolymers of formula (I) can be carried out using various polymerization techniques such as solution, emulsion, microemulsion, inverse emulsion, and/or bulk polymerization, as well as other technologies that are available to those who are skilled in the art. The polymerizations can be carried out with or without free radical initiators and with various initiator concentrations. The cationic terpolymers can also be prepared in such a way that the architecture of the resulting terpolymers is random, block, alternating or core-shell, and with or without the use of polymerization regulators such as nitroxyl ethers or other types of nitroxyl radicals.
Examples of the suitable initiators include, but are not limited to, persulfates such as ammonium persulfate (APS); peroxides such as hydrogen peroxide, t-butyl hydroperoxide, and t-butyl peroxy pivalate; azo initiators such as 2,2′-azobis(2-amidinopropane) dihydrochloride, 4,4′-azobis-4-cyanovaleric acid and 2,2′-azobisisobutyronitrile, and redox initiator systems such as t-butyl hydroperoxide/Fe(II) and ammonium persulfate/bisulfite. Aqueous solution polymerization using ammonium persulfate (APS) is the preferred method for preparing the amino-functionalized base cationic polymer of the preferred monomers DADMAC and DAA (or MDAA).
The amount of the free radical initiator used in the polymerization process depends on the total monomer concentration and the type of monomers used, and may range from about 0.2 to about 5.0 wt % of total monomer charge to achieve more than 99% of total monomer conversion.
In one embodiment the polymerization is carried out in the substantial absence of oxygen. Oxygen can be removed from the reaction medium by applying vacuum with agitation or by purging with an inert gas such as nitrogen or argon.

The personal care compositions of the present invention may contain one or more additional skin care or hair care components. In a preferred embodiment, where the composition is to be in contact with human or animal keratinous tissue, the additional components should be suitable for application to keratinous tissue, that is, when incorporated into the composition they are suitable for use in contact with human or animal keratinous tissue without undue toxicity, incompatibility, instability, allergic response, and the like within the scope of sound medical judgment.
The instant compositions may further comprise, cosmetically acceptable ingredients and adjuvants of component (b) selected, in particular but not limited to, from among fatty substances, organic solvents, oil structurants, surfactants, emulsifiers, thickeners, organic cationic deposition polymers, demulcents, opacifiers, additional colorants, effect pigments, additional stabilizers, emollients, antifoaming agents, moisturizing agents, antioxidants, vitamins, peptides, amino acids, botanical extracts, particulates, perfumes, preservatives, polymers, fillers, sequestrants, propellants, alkalinizing or acidifying agents or other optional ingredients customarily formulated into cosmetics or other personal care compositions according to the invention.

The oils may be selected from among animal, vegetable, mineral or synthetic oils and, in particular, from among liquid paraffin, paraffin oil, silicone oils, volatile or otherwise, isoparaffins, polyolefins, fluorinated or perfluorinated oils. Likewise, the waxes may be animal, fossil, vegetable, mineral or synthetic waxes which are also known per se.
Exemplary organic solvents may include the lower alcohols and polyols.
Of course, one skilled in this art will take care to select this or these optional additional compounds and/or their quantities such that the advantageous properties, in particular the resistance to water, the stability, which are intrinsically associated with the sunscreen compositions in accordance with the invention are not, or not substantially, altered by the addition(s) envisaged.
The CTFA Cosmetic Ingredient Handbook, Second Edition (1992) describes a wide variety of non-limiting cosmetic and pharmaceutical ingredients commonly used in the personal care industry, which are suitable for use in the personal care compositions of the present invention.
The present invention may optionally comprise an oil structurant. The structurant can provide the dispersed phase with the correct rheological properties. This can aid in providing effective deposition and retention to the skin, the structured oil or oil phase should have a viscosity in the range of 100 to about 200,000 poise measured at 1 Sec-1, preferably 200 to about 100,000 poise, and most preferably 200 to about 50,000 poise. The amount of structurant required to produce this viscosity will vary depending on the oil and the structurant, but in general, the structurant will preferably be less than 75 weight percent of the dispersed oil phase, more preferably less than 50 weight percent, and still more preferably less than 35 weight percent of the dispersed oil phase.
The structurant can be either an organic or inorganic structurant. Examples of organic thickeners suitable for the invention are solid fatty acid esters, natural or modified fats, fatty acid, fatty amine, fatty alcohol, natural and synthetic waxes, and petrolatum, and the block copolymers sold under the name KRATON by Shell. Inorganic structuring agents include hydrophobically modified silica or hydrophobically modified clay. Nonlimiting examples of inorganic structurants are BENTONE 27V, BENTONE 38V or BENTONE GEL MIO V from Rheox; and CAB-O-SIL TS720 or CAB-O-SIL M5 from Cabot Corporation.
Structurants meeting the above requirements with the selected skin compatible oil can form 3-dimensional network to build up the viscosity of the selected oils. It has been found that such structured oil phases, i.e., built with the 3-dimensional network, are extremely desirable for use as wet-skin treatment compositions used in bathing. These structured oils can deposit and be retained very effectively on wet skin and retained after rinsing and drying to provide long-lasting after wash skin benefit without causing a too oily/greasy wet and dry feel. It is believed that the highly desirable in-use and after-use properties of such structured oils are due to their shear thinning rheological properties and the weak structure of the network. Due to its high low-shear viscosity, the 3-dimensional network structured oil can stick and retain well on the skin during application of the skin conditioner. After being deposited on the skin, the network yields easily during rubbing due to the weak structuring of the crystal network and its lower high-shear viscosity.
A wide variety of surfactants can be useful herein, both for emulsification of the dispersed phase as well as to provide acceptable spreading and in use properties for non-lathering systems.

Preferred cationic cellulose polymers are the salts of hydroxyethyl cellulose reacted with trimethyl ammonium substituted epoxide, referred to in the industry (CTFA) as Polyquaternium 10 which are available from Amerchol Corp. (Edison, N.J., USA) in their POLYMER KG, JR and LR series of polymers with the most preferred being KG-30M.
Other suitable cationic deposition polymers include cationic guar gum derivatives, such as guar hydroxypropyltrimonium chloride, specific examples of which include the Jaguar series (preferably JAGUAR C-17) commercially available from Rhodia Inc., and N-HANCE polymer series commercially available from Aqualon.
Other suitable cationic deposition polymers include synthetic cationic polymers. The cationic polymers suitable for use in the personal cleansing composition herein are water soluble or dispersible, non cross linked, cationic polymers having a cationic charge density of from about 4 meq/gm to about 7 meq/gm, preferably from about 4 meq/gm to about 6 meq/gm, more preferably from about 4.2 meq/gm to about 5.5 meq/gm. The select polymers also must have an average molecular weight of from about 1,000 to about 1 million, preferably from about 10,000 to about 500,000, more preferably from about 75,000 to about 250,000.
A non limiting example of a commercially available synthetic cationic polymer for use in the cleansing compositions is polymethyacrylamidopropyl trimonium chloride, available under the trade name POLYCARE 133, from Rhodia, Cranberry, N.J., U.S.A.
Other non limiting examples of optional ingredients include benefit agents that are selected from the group consisting of vitamins and derivatives thereof (e.g., ascorbic acid, vitamin E, tocopheryl acetate, and the like); sunscreens; thickening agents (e.g., polyol alkoxy ester, available as CROTHIX from Croda); preservatives for maintaining the anti microbial integrity of the cleansing compositions; anti-acne medicaments (resorcinol, salicylic acid, and the like); antioxidants; skin soothing and healing agents such as aloe vera extract, allantoin and the like; chelators and sequestrants; and agents suitable for aesthetic purposes such as fragrances, essential oils, skin sensates, pigments, pearlescent agents (e.g., mica and titanium dioxide), lakes, colorings, and the like (e.g., clove oil, menthol, camphor, eucalyptus oil, and eugenol), antibacterial agents and mixtures thereof. These materials can be used at ranges sufficient to provide the required benefit, as would be obvious to one skilled in the art.
The following examples describe certain embodiments of this invention, but the invention is not limited thereto. It should be understood that numerous changes to the disclosed embodiments could be made in accordance with the disclosure herein without departing from the spirit or scope of the invention. These examples are therefore not meant to limit the scope of the invention. Rather, the scope of the invention is to be determined only by the appended claims and their equivalents. In these examples all parts given are by weight unless otherwise indicated.
Example 1
Synthesis of DADMAC/DAA Copolymer
A 1-liter reactor equipped with a condenser, a thermometer, a nitrogen inlet and an overhead agitator is charged with 260 g of 66% DADMAC monomer, 34.5 g of diallylamine (DAA), 35.0 g of HCl solution, 6.0 g of deionized water, and 0.4 g of 20% Na 4 EDTA solution. The polymerization mixture is purged with nitrogen and heated with agitation to a temperature of 80 C. An aqueous solution containing 2.1 g of ammonium persulfate (APS) is slowly fed to the reaction mixture over 190 minutes. The reaction temperature is allowed to increase to above 90 C and then maintained at 90 to 100 C during the APS feed period. After the APS feed, the reaction temperature is held at 95 C for about 30 minutes. Then an aqueous solution containing 6 g of sodium metabisulfite (MBS) is added over 30 minutes. The reaction mixture is held at 95 C for another 30 minutes to complete the polymerization (above 99% conversion). The polymer solution is then diluted with sufficient water to about 35% solids by weight and cooled to room temperature. The final product has a Brookfield viscosity of 9100 cps at 25 C (using a Brookfield LV4 spindle at 30 rpms) and 33% polymer solids.
Example 2
Synthesis of DADMAC/DM Copolymers
Following the same procedure as Example 1 the following polymers (in Table 1 below) are synthesized. The final product viscosities are measured at 25 C using a Brookfield viscometer using a Brookfield LVT #3 spindle at 12 rpms. The viscosity results are shown in Table 1 below.

Example 3
DADMAC/DAA/Siloxane Terpolymer
A 0.5-liter reactor fitted with a mechanical stirrer, addition funnel and condenser is charged with 50 grams (14.5 mmol secondary amine, NH) of the base polymer (2D) from Example 2. 5.0 g of 2-propanol is added and heated to 70 C. The reactor content is adjusted with 1.3 g of 50% NaOH aqueous solution to a pH of 9.0 to 10.0 and heated to 70 C with agitation. After the pH adjustment, 0.5 g (5.8 mmol) of linear diepoxypolydimethylsiloxane (TEGO IS 4150, Degussa) is added into the reactor. The crosslinking reaction is maintained at about 70 C and the viscosity of the reaction solution is monitored with an agitator torque meter. The viscosity of the reactor contents, as is indicated by the torque meter reading, increases with reaction time. 3.5 g of 2-propanol was added to aid in viscosity reduction. While the viscosity shows little further increase with increasing reaction time after about four hours, the reaction mixture is held at 70 C for another 2 hours. The reaction mixture is heated to 90 C and the 2-propanol is distilled over. After distilling for 1 hour, the amount of 2-propanol remaining was less than 0.2% as determined by gas chromatography. A concentrated HCl solution and deionized water are added to adjust the pH to about 5. The resulting polymer product is a homogeneous, green-yellow emulsion-looking solution having 13.2 weight percent of polymer solids. The functionalized cationic terpolymer contains about 2.5 weight percent of the difunctional polysiloxane, which provides hydrophobic siloxane functionality to the copolymer.
Example 4
DADMAC/DAA/Siloxane Terpolymer
The procedure of Example 3 is followed except that 3.0 g instead of 0.5 g linear diepoxy polydimethylsiloxane (TEGO IS 4150, from Degussa) cross-linking agent is added. The resulting polymer product is a homogeneous, green-yellow emulsion-looking solution with 3.5 weight percent of polymer solids. The terpolymer contains about 13.3 weight percent of cross-linked polysiloxane which provides substantial hydrophobic siloxane functionality to the cationic terpolymer.
Example 5
DADMAC/DAA/Siloxane Terpolymer
The procedure of Example 3 is followed except that 1.5 g instead of 0.5 g cross-linking siloxane agent is added. The resulting polymer product is a homogeneous, green-yellow emulsion-looking solution with 11.3 weight percent of polymer solids. The terpolymer contains about 6.7 weight percent of crosslinked polysiloxane which provides substantial hydrophobic siloxane functionality to the cationic terpolymer.

DADMAC/DAA/Polyethylene Glycol Terpolymer
A 0.5-liter reactor fitted with a mechanical stirrer, addition funnel and condenser is charged with 26.9 grams (2.5 mmol secondary amine, NH) of the base polymer (2F) from Example 2. 33.9 g of water is added and heated to 70 C. The reactor content is adjusted with 0.1 g of 50% NaOH aqueous solution to a pH of 9.0 to 10.0 and heated to 70 C. with agitation. After the pH adjustment, 0.26 g (0.5 mmol) of linear polyethyleneglycol diglycidylether (PEGDGE, Aldrich Chemical, average molecular weight is 526 Daltons) is added into the reactor. The reaction is maintained at about 70 C and the viscosity of the reaction solution is monitored with an agitator torque meter. The viscosity of the reactor contents, as is indicated by the torque meter reading, increases with reaction time. Water (277.2 g) is added over the course of the reaction hold time to aid in viscosity reduction. While the viscosity shows little further increase with increasing reaction time after about four hours, the reaction mixture is held at 70 C for another 2 hours. After a total reaction time of six hours at 70 C, the level of PEGDGE remaining is determined to by 0% by gas chromatography. A concentrated HCl solution and deionized water are added to adjust the pH to about 4. The resulting polymer product is a homogeneous, yellow emulsion-looking solution having 3.4 weight percent of polymer solids.

Example 18
DADMAC/DAA/Siloxane Terpolymers Further Functionalized with C12-Alkyl Substituted Quaternary Ammonium Group
50.0 g (42 mmol/eq. wt. based on DM in sample) of the base polymer 2A from Example 2, 10.1 g of deionized water and 3.3 g 50% NaOH solution are placed into a round-bottomed flask equipped with a stirrer, nitrogen inlet and a thermoregulator and heated. When the temperature reaches 70 C, 30.2 g (33.5 mmol) of a 38% solution of 3-chloro-2-hydroxypropyl-dimethyldodecylammonium chloride (QUAB 342 from Degussa) and 8 g of 2-propanol are added to the flask. An exotherm is observed with an increase in temperature from 65-70 C. When the rise in temperature subsides, the reaction mixture is maintained at 65 C for three hours with stirring. During the reaction 6.0 g of deionized water is added to aid in viscosity control. At this time the consumption of QUAB 342 is determined to be >99% by chloride titration. After this time, the mixture is cooled to room temperature and 179 g of deionized water and 1.5 g of a 2.3% HCl/water solution is added to adjust the pH. The functionalized DADMAC/DAA copolymer is obtained as a clear viscous yellow mixture of 12.8 wt. % solids. The intermediate product has a Brookfield viscosity of 4900 cps at 25 C (using a Brookfield LV3 spindle at 12 rpms) at 12.8% polymer solids.
An aliquot of the reaction mass (20.1 g) is taken and added to a separate reaction flask and the procedure of Example 3 is followed except that 0.2 g instead of 0.5 g linear diepoxy polydimethylsiloxane (TEGO IS 4150, from Degussa) reactant is added. The resulting terpolymer product is a homogeneous, yellow emulsion-looking solution with 3.4 weight percent of polymer solids.
