(en)CROSS REFERENCE TO RELATED APPLICATIONS
This application is a national phase application of PCT/US2008/012365 filed Oct. 31, 2008, which is a continuation of U.S. application No. 12/050,543 filed Mar. 18, 2008, which claims priority to U.S. Provisional Application No. 60/984,753 filed Nov. 2, 2007.


FIELD OF THE INVENTION
The present invention relates to novel copolymers formed as the reaction product of epoxy compounds and amino silanes.
BACKGROUND OF THE INVENTION
U.S. Pat. No. 4,062,999 A describes a process for treating textile fibers with a mixture of an amino functional silane and an epoxy functional silicone. The unreacted mixture is applied to the fiber then heat treated in an oven.
U.S. Pat. No. 4,359,545A describes the process of reacting an amino functional silicone and an epoxy functional silicone onto a textile surface. The blend is applied to a textile then heat-treated in an oven.
U.S. Pat. No. 5,384,340 describes the use of a moisture and or photo curable coatings system. The process involves first reacting an epoxy or methacryl functional silane with an excess of an amino functional silicone. The remaining unreacted amino groups are then reacted with an epoxy or isocyano functional vinyl containing molecule. The resulting material contains both moisture curable alkoxy silane groups and free radical curable vinyl groups.
EP 1,116,813A1 describes a textile treatment composition containing siloxanes having epoxy- and glycol-functionalities and either an aminosilane or a silicone quaternary ammonium compound. The composition is preferably formulated as an aqueous emulsion. The emulsion is applied to the textile surface followed by heat treatment to cure the mixture.
U.S. Pat. No. 5,102,930 A describes a silicone-based fabric finishing agent that is suitable for finishing a fabric material containing keratinous fibers, e.g., wool. The fabric finishing agent is an aqueous emulsion of a hydroxy-containing organopolysiloxane with an admixture of a mixture of colloidal silica and a reaction product of an amino-functional alkoxy silane or a hydrolysis product thereof with an acid anhydride, an epoxy-functional alkoxy silane compound and a curing catalyst.
U.S. Pat. No. 6,475,568 B1 describes the synthesis of non-crosslinkable silicone polyether non-(AB)n materials that do not contain silane or reactive groups. Modified silicones can exhibit a variety of physical properties. The polymers can be modified to be hydrophilic, lipophilic and hydrophobic depending on the nature of the organic substituents. Recently, linear alternating copolymers and linear random copolymers have been made using alkyl or polyether, and polydimethylsiloxane units. These materials have shown utility in a variety of applications including personal care (hair conditioners, skin care and color cosmetics), textile treatments, hard surface modifiers, agricultural adjuncts, and the like. Unfortunately these materials are liquids and show limited durability when applied to a surface.

Reference is made to substances, components, or ingredients in existence at the time just before first contacted, formed in situ, blended, or mixed with one or more other substances, components, or ingredients in accordance with the present disclosure. A substance, component or ingredient identified as a reaction product, resulting mixture, or the like may gain an identity, property, or character through a chemical reaction or transformation during the course of contacting, in situ formation, blending, or mixing operation if conducted in accordance with this disclosure with the application of common sense and the ordinary skill of one in the relevant art (e.g., chemist). The transformation of chemical reactants or starting materials to chemical products or final materials is a continually evolving process, independent of the speed at which it occurs. Accordingly, as such a transformative process is in progress there may be a mix of starting and final materials, as well as intermediate species that may be, depending on their kinetic lifetime, easy or difficult to detect with current analytical techniques known to those of ordinary skill in the art.
Reactants and components referred to by chemical name or formula in the specification or claims hereof, whether referred to in the singular or plural, may be identified as they exist prior to coming into contact with another substance referred to by chemical name or chemical type (e.g., another reactant or a solvent). Preliminary and/or transitional chemical changes, transformations, or reactions, if any, that take place in the resulting mixture, solution, or reaction medium may be identified as intermediate species, master batches, and the like, and may have utility distinct from the utility of the reaction product or final material. Other subsequent changes, transformations, or reactions may result from bringing the specified reactants and/or components together under the conditions called for pursuant to this disclosure. In these other subsequent changes, transformations, or reactions the reactants, ingredients, or the components to be brought together may identify or indicate the reaction product or final material.
In describing the products of the instant invention as a reaction product of initial materials reference is made to the initial species recited and it is to be noted that additional materials may be added to the initial mixture of synthetic precursors. These additional materials may be reactive or non-reactive. The defining characteristic of the instant invention is that the reaction product is obtained from the reaction of at least the components listed as disclosed. Non-reactive components may be added to the reaction mixture as diluents or to impart additional properties unrelated to the properties of the composition prepared as a reaction product. Thus for example finely divided solids such as pigments may be dispersed into the reaction mixture, before during or after reaction to produce a reaction product composition that additionally comprises the non-reactive component, e.g. a pigment. Additional reactive components may also be added; such components may react with the initial reactants or they may react with the reaction product; the phrase “reaction product” is intended to include those possibilities as well as including the addition of non-reactive components.
Optionally the reaction of component A with component B can be conducted in the presence of a primary or secondary amine that may or may not possess a reactive alkoxy silane moiety. The result will be a reaction product of A, B, and the primary or secondary amine. Examples of these primary amines are; methylamine, ethylamine, propylamine, ethanol amine, isopropylamine, butylamine, isobutylamine, hexylamine, dodecylamine, oleylamine, aniline aminopropyltrimethylsilane, aminopropyltriethylsilane, aminomorpholine, aminopropyldiethylamine benzylamine, napthylamine 3-amino-9-ethylcarbazole, 1-aminoheptaphlorohexane, 2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-pentadecafluoro-1-octanamine and the like. Examples of secondary amines are; methylethylamine, methylhexylamine, methyloctadecylamine, diethanolamine, dibenzylamine, dihexylamine dicyclohexylamine, piperidine, pyrrolidine phthalimide, and the like. Polymeric amines may also be used such.
Applications for Embodiments of the Invention
The product of the reaction of A, an oxirane or oxetane compound possessing two or more oxirane or oxetane groups per molecule and B, an aminosilane, results in a polymer that contains alkoxy silane functional moieties covalently bond to the polymer chain. These alkoxy silane groups may be activated particularly by hydrolysis and undergo further reactions leading to a cross-linked network. The cross-linking mechanism of silanes is usually a two-step process. The first step usually involves the hydrolysis of an alkoxy silane to form silanols. The second step usually involves the condensation of the silanol groups so produced with themselves or with other reactive organic groups. The reaction between two silanol groups leads to a thermally stable siloxane bond. Silanol groups may also condense reversibly with organic moieties such as alcohols, carboxylic acids, amines, mercaptans, and ketones (other reactive groups). The bonds that are formed are less stable than the siloxane bonds. However when a cross-linked network is formed the rate of the reverse reaction may be severely reduced or even stopped.
The compositions of the present invention may be utilized as pure components, mixtures, or emulsions. As is generally known, emulsions comprise at least two immiscible phases one of which is continuous and the other which is discontinuous. Further emulsions may be liquids or gases with varying viscosities or solids. Additionally the particle size of the emulsions may render them microemulsions and when sufficiently small microemulsions may be transparent. Further it is also possible to prepare emulsions of emulsions and these are generally known as multiple emulsions. These emulsions may be:
aqueous emulsions where the discontinuous phase comprises water and the continuous phase comprises the composition of the present invention;
aqueous emulsions where the discontinuous phase comprises the composition of the present invention and the continuous phase comprises water;
non-aqueous emulsions where the discontinuous phase comprises a non-aqueous hydroxylic solvent and the continuous phase comprises the composition of the present invention; and
non-aqueous emulsions where the continuous phase comprises a non-aqueous hydroxylic organic solvent and the discontinuous phase comprises the composition of the present invention.
Depending on the choice of component A and component B it is possible to alter the hydrophilic or lipophilic properties of the resulting reaction product. Thus depending on the hydrophilic lipophilic balance, the resulting reaction product may be soluble in polar aqueous or hydroxylic solvents or it may be soluble in non-polar solvents such as oils, low molecular weight siloxanes and silicones and the like.

Application Example 3 Cross Hatch Adhesion
Using the procedure from the standard test method measuring adhesion by tape test (ASTM D3359-87) the crosshatch adhesion performance was evaluated. The example formulations were coated on untreated steel and allowed to cure at room temperature for 4 days. Test method B was employed where a lattice pattern was scratched into the film. The tape was applied to the scratched surface then removed. The resulting coating was evaluated for pealing and missing portion of film. No such defects were detected when all four example formulations were tested.
Application Example 4 Solvent Resistance
Using the standard test method for measuring methyl ethyl ketone (MEK) resistance (ASTM D4752-87) was employed. The coated steel substrates were first washed with deionized water and the immediately insulted with an automated device equipped with a hammer-head and a saturated with MEK cheesecloth. The samples were rubbed for 15 times then examined for marring. The process was repeated using 120 oscillations and again examined for marring. The results are shown in the table below.

Anti-Staining Applications for Hardsurfaces Examples
The following examples demonstrate he utility of the silane ABn's for use as anti-staining coatings for the protection of hard surfaces.
Procedure for Making Coating Formulations
Synthetic Example C, J, L, & M were diluted to a 20% aqueous formulation and neutralized with acetic acid (pH 7). The hard surfaces tested in this application were Terracotta and Marble (3″×3″). Half of each tile was treated by adding 0.5 mL of the formulation to each tile. The coating was then smoothed using an applicator in order to have a uniform coating on half of each tile. The tiles were allowed to cure overnight at ambient temperature. The control formula was a commercial hard surface sealer from HG international. The following day each tile was subjected to two drops of staining solution. The stains are listed in the table below. The stains were allowed to sit at ambient temperature on the surface for 16 hr. Then the tiles were washed with a wet sponge and Dawn dishwashing detergent. Once dry the tiles were visually rated and given a score between 0-10, 0 being no residue left behind while 10 was given if a dark stain was evident. There is a marketable improvement in stain prevention when compared to the untreated tiles.

Non-Woven Application Examples
Treatment of Spun Polypropylene
The formulations were made accordingly to the table below. All formulations were neutralized with acetic acid to pH 7. Each example formula was applied to a 100% polypropylene (PP) nonwoven coverstock 100% (Spunbonded Polypropylene 22 g/m2) at 0.5% add-on at 100% pick-up. The nonwoven finish was applied to PP diaper coverstock by the padding method and drying conditions in a Werner Mathis AG dryer for 90 sec @ 105° C. After treatment the PP diaper coverstock was placed at ambient temperature for 24 hrs before any physical evaluations take place. These treated PP diaper coverstock materials were used for all the non-woven application examples.

Run-Off Application

Run-Off experiments were performed following the standard Edana 152.0-99. Given in the table is the percent run-off of a 0.9% sodium chloride solution when applied to a piece of treated spun polypropylene held at a 25° angle. Two different sets of treatments were chosen. Example formulations 11 and 12 are hydrophobic treatment while examples 13 and 14 are hydrophilic. An untreated sheet of polypropylene was used for comparison.

Run-Off experiments were performed following the standard Edana Strike Through Time 150.3-96. Given in the table is the percent run-off of a 0.9% sodium chloride solution when applied to a piece of treated spun polypropylene held at a 25° angle. Two different sets of treatments were chosen. Example formulations 11 and 12 are hydrophobic treatment while examples 13 and 14 are hydrophilic. An untreated sheet of polypropylene was used for comparison.

Hydrostatic Pressure Test Inda Standard Test IST 80.4

A Hydrodrostatic pressure test was performed on the treated polypropylene to test resistance to water penetration when a column of water was placed on the surface. The treated polypropylene was sandwiched between two pieces of plastic with a 2″ circular hole in both. The upper piece was attached to a graduated column. Water was introduced through in inlet just over the PP material at a rate that did not allow for a vortex to form. A mirror was positioned below the apparatus and the water was added to the column. The height of the water was recorded once drops of water formed and released from the bottom of the apparatus. The data is shown in the table below. For formulations 13 and 14 no buildup occurred and the water immediately penetrated and began to flow through the polypropylene.
Water Height Example Formulation 11 1.3 cm Example Formulation 12 1.3 cm Example Formulation 13 Instant Example Formulation 14 Instant Untreated 1.0 cm
Migration

The effect of migration of was examined for the treated polypropylene diaper coverstock. Migration of the hydrophilic coating to adjoining untreated polypropylene is highly undesirable. Dry migration will result in leaks in the final product. The following procedure was used to examine the resistance to migration of the coated polypropylene. Untreated 100% spunbonded SMS (Spunbonded/Meltblown/Spunbonded) polypropylene webs were placed beneath and above 100% spunbonded polypropylene nonwoven web treated with either example formulations 13 or 14. A weight (0.5 lb./in 2 ) was placed on the nonwovens for 1 week at 50° C. to simulate storage and all layers evaluated for hydrophilicity (AATCC Test Method 79-1995). The desired result is to have the top and bottom layers remain hydrophobic and the treated nonwoven to remain hydrophilic. Any change in hydrophilicity of either the top or bottom layer of polypropylene is considered migration. The test was terminated at 300 sec per measurement.

No migration was found when either hydrophilic treatment was used. For comparison the process was repeated with a non-curing commercial diaper coverstock treatment. The top and bottom layers exhibited a strike through time of 90-100 seconds. Clearly the hydrophilic treatment migrated from the treated PP to the non-treated PP.

The synthetic example O, P, R or L was combined with deionized water in a beaker, stirred with an overhead stirrer then acidified to pH 5 with acetic acid.
Formulation and Preparation Procedure for Making a Microemulsion of Control Formulation 2
A 20% microemulsion of Magnasoft Derma NT was made by the addition of 25.0 grams of a commercial polysilicone quat (Momentive Performance Materials) into a disposable beaker to 10.5 grams of TDA-6 and 1.8 grams of TDA-12 (both surfactants made by Ethox). The mixture was stirred using a mechanical stirrer, at moderate speed (˜600 rpm) for 5 minutes. Separately a solution of 62.0 grams of deionized water, 0.4 grams of acetic acid, and 0.3 grams of sodium acetate was combined in an addition funnel. The water, acetic acid, and sodium acetate solution was added dropwise over 30 minutes. After the final addition the emulsion was stirrer for an additional 10 minutes.
For treatment in the Pad Bath a dilution of the 20% microemulsion was required. A mechanical stirrer was used and deionized water was added with moderate stirring (˜600 rpm) until all the material has been evenly dispersed at an actives concentration of 0.5%.
Treatment by Pad Bath
The diluted treatments (0.5% actives, 150 g) were poured into a disposable beaker. A piece of untreated fabric was weighed and the mass was recorded. The fabric was immersed in the treating solution for 30 seconds or until completely wet. The saturated fabric was passed through a Werner Mathis padder fitted with 4.5″ rubber rollers (roller speed—6 M/min, roller pressure—0.5 bar). The fabric was reweighed and the roller pressure was adjusted until 100% wet pick up was achieved. Immediately following the treatment the swatch was placed in a fabric oven at 130° C. for 5 minutes to dry the sample.
Fabric Conditioning
Prior to any physical evaluation of the treated and untreated fabrics, the swatches were placed in an environmental chamber set at 21° C. and 65% RH for a minimum of 24 hours.
Wet Out
The ability of the treatment to increase (hydrophobicity) or decrease (hydrophilicity) the time required for a drop of water to penetrate the surface of the fabric. This test was performed in accordance with the AATCC Test Method 79-1992. A piece of treated or untreated cotton knit fabric was secured in a 6″ embroidery ring. Care was taken as to not stretch the fabric but the fabric was taut and free of folds or wrinkles. A drop of deionized water was applied onto the fabric via a dropper and a timer was started. The timer was stopped when the drop of water completely penetrated the fabric and was record in seconds. The process was repeated 6 times at different positions for each fabric. The value reported is the average of these readings, shown in the table below. The test was terminated at 600 seconds. A value of 600 seconds indicates that the drop never penetrated the surface of the fabric.

Wicking

A wicking test was performed in order to evaluate how well the treatments enhance or deter the wicking of water through the fabric. This test was performed in accordance with the ASTM D-5237 test protocol. A 2″×7″ strip of treated or untreated fabric was cut from different sample sheets. One end the fabric was marked with a pencil line ˜15 mm from the edge. 2 standard metal paper clips were fastened between this line and the edge of the sample. The other end of the fabric was secured a stand with a large (#100) binder clip. The fabric was immersed up to the pencil line in a beaker of colored water. After 6 minutes the fabric samples were removed from the water and the distance from the pencil line to the final position of the wicked water was measured with a ruler and recorded in millimeters. The procedure was repeated 4 times and the measurement were averaged and given in the table below.

Durability (Machine Wash/Dry)

The durability study examined how long the treatment remained on cotton knit fabric after repetitive washing and drying. A treated 11″×11″ swatch of fabric was placed in a top loader washing machine. The machine was set to a regular wash cycle for a wash period of 12 minutes with a 19 gallon water fill and a temp of 87° F. The detergent used was 60 grams of AATCC Standard Reference Detergent. Once washed the fabric swatches were dried by placing them in a front loader dryer set on timed dry, high heat for 30 minutes. The process was repeated for the given number of wash/dry cycles as dictated in the table below. The fabric samples were then exposed to a BF 3 digestion and the silicone content was measured using a GC. The values reported are the percent silicone the remains after the number of washes.

Spray Test

An alternate test for durability was performed. A Spray Test was run according to AATCC test method 22-1989. Treated cotton knit fabric was washed in the same manner as described in the Durability section above for 1, 3, 5, 10 and 20 wash/dry cycles. The fabric was secured a 6″ embroidery ring. Care was taken so that the fabric did not stretch but it was taut and free of folds or wrinkles. The assembly was placed on the spray test apparatus that consisted of stand holding a jig set at a 45° angle positioned below a large funnel and showerhead. 250 mL of deionized water was poured through the funnel and showerhead onto the test specimen. The specimen/ring was removed and visually rated 0-100 by comparing its appearance to the spray test rating standard. The control sample was an untreated piece of cotton knit. The results are shown in the table below. The high numbers of 121-113 indicate that the surface remains hydrophobic even after 20 washes.
