Abstract:
An organopolysiloxane composition which comprises:a) organopolysiloxane I of the general formula â€ƒwherein each R1 is, independently, an alkyl group of from 1 to 4 carbon atoms, R2 is a divalent hydrocarbon group, R3 is hydrogen or a monovalent hydrocarbon group, each A is, independently, an R1 group or an R2(NHCH2CH2)cNHR3 group, provided, that at least one A is an R2(NHCH2CH2)cNHR3 group, a is from 1 to about 1000, b is from 0 to about 100 and c is from 0 to about 10; b) organopolysiloxane II of the general formula (AB)nA â€ƒwherein n is from 2 to about 1000, A is a polysiloxane unit of the general formula [X(CaH2aO)bR2(Si[R1]2O)cR2(OCaH2a)bX], â€ƒB is a polyalkyleneoxide unit of the general formula [YO(CaH2aO)dY], each R1 is, independently, an alkyl group of from 1 to 4 carbon atoms, R2 is a divalent organic group, X and Y are divalent organic groups selected from a secondary or tertiary amine and a ring-opened epoxide such that when X is a ring-opened epoxide, Y is a secondary or tertiary amine and when X is a secondary or tertiary amine, Y is a ring-opened epoxide, each a is, independently, from 2 to about 4, each b is independently from 0 to about 100, c is from 1 to about 500, d is from 0 to about 100 and the sum of b and d is from 1 to about 100; c) organopolysiloxane III of the general formula A(Si[R1]2O)x(Si[R1][E]O)y(Si[R1][G]O)zSi(R1)2A â€ƒwherein each R1 is, independently, an alkyl group of from 1 to 4 carbon atoms, E is a monovalent organic group containing at least one epoxy group, G is an B(R2)bO(C2H4O)c(C3H6O)dR3 group in which R2 is a divalent organic group, R3 is hydrogen or a monovalent hydrocarbon group, acyl group or monoester carbonate group, b is 0 or 1, c is from 0 to about 50, d is from 0 to about 50 and the sum of c and d is from 1 to about 100, each A is, independently, an R1 or E group, x is from 0 to about 2000, y is from 0 to about 2000, z is from 1 to about 100 and the sum of x and y is from 1 to about 2000; and, d) organopolysiloxane IV of the general formula A(Si[R1]2O)x(Si[R1][G])ySi(R1)2A â€ƒwherein each R1 is, independently, an alkyl group of from 1 to 4 carbon atoms, G is an B(R2)bO(C2H4O)c(C3H6O)dR3 group in which R2 is a divalent organic group, R3 is hydrogen, a monovalent hydrocarbon group, an acyl group or a monoester carbonate group, b is 0 or 1, c is from 0 to about 50, d is from 0 to about 50 and the sum of c and d is from 1 to about 100, each A is, independently, an R1 group or a monovalent organic group containing at least one epoxy group; x is from 0 to about 2000, y is from 0 to about 2000, and the sum of x and y is from 1 to about 2000.
