Abstract
A curable composition useful for treating textiles to impart thereto upon the curing of one or more textile use-enhancing characteristics includes a first macromonomer (i) which is a polysiloxane possessing two or more terminal functional groups selected from the group consisting of hydroxyl, alkoxy and combinations thereof, a second macromonomer (ii) which is a polysiloxane containing two or more hydrosilyl (≡C—SiH) groups, catalyst (iii) and, optionally, one more additional component(s) (iv) such as surfactant(s), water, etc.

A curable composition comprising:
- at least one macromonomer (i) which is a polysiloxane of general formula (I):
- MAaDBbDCcTDdTEeMAa (I)

- R5 and R7, each instance, is independently a monovalent hydrocarbon group of from 1 to 22 carbon atoms and substituted with at least one amino and/or oxirane group;
- and,
- 1≦a≦19, 1≦b≦9999, 1≦c≦19, 0≦d≦9, 0≦e≦9 and 0≦y≦3;

- at least one catalyst (iii) for the copolymerization reaction of macromonomer(s) (i) and (ii);
- and,
- optionally, at least one additional component (iv) selected from the group consisting of surfactant(s) and aqueous surfactant(s).
A method for treating a textile to impart at least one property-enhancing characteristic thereto comprising:
- a) applying to a textile an amount of curable composition which after undergoing curing provides at least one cured resin which is effective to impart at least one textile property enhancing characteristic thereto, the curable composition comprising:
- at least one monomer (i) which is a polysiloxane of general formula (I):
- MAaDBbDCcTDdTEeMAa (I)
- wherein
- MA is (OR1)y(R2)3-ySiO1/2;
- DB is R32SiO2/2;
- DC is R4R5SiO2/2;
- TD is R6SiO3/2;
- and,
- TE is R7SiO3/2;
- in which
- R1, each instance, is independently hydrogen or a monovalent hydrocarbon group of from 1 to 22 carbon atoms;
- R2, R3, R4 and R6, each instance, is independently a monovalent hydrocarbon or alkoxy group of from 1 to 22 carbon atoms;
- R5 and R7, each instance, is independently a monovalent hydrocarbon group of from 1 to 22 carbon atoms and substituted with at least one amino and/or oxirane group;
- and,
- 1≦a≦19, 1≦b≦9999, 1≦c≦19, 0≦d≦9, 0≦e≦9 and 0≦y≦3;
- at least one macromonomer (ii) which is an oligomer or polymer containing at least two silylhydride functional groups per molecule;
- at least one catalyst (iii) for the copolymerization reaction of macromonomer(s) (i) and (ii);
- and,
- optionally, at least one additional component (iv) selected from the group consisting of surfactant(s) and aqueous surfactant(s);
- and,
- b) subjecting the curable composition to curing conditions to produce a cured resin composition of macromonomer(s) (i) and (ii) and impart to the textile at least one property-enhancing characteristic.
