Claim:
A composition comprising (A) at least one copolymer of the formula (1) and (B) at least one compound of the formula (2) in which R are the same or different and are hydrogen or a monovalent SiC-bonded, optionally substituted hydrocarbyl radical, Y are the same or different and are divalent, optionally substituted hydrocarbyl radicals, X are the same or different and are divalent SiC-bonded, optionally substituted hydrocarbyl radicals which are optionally interrupted by oxygen atoms, A are the same or different and are oxygen, sulfur, or an amino group —NR 1 —, R 1 are the same or different and are hydrogen or an optionally substituted hydrocarbyl radical, D are the same or different and are an alkylene radical which is optionally substituted by halogen, C 1 -C 6 -alkyl or C 1 -C 6 -alkyl ester and has 1 to 700 carbon atoms, in which mutually nonadjacent methylene units are optionally replaced by —O—, —COO—, —OCO— or —OCOO— groups, B are the same or different and are hydrogen, an OCN—Y—NH—CO— radical, an H 2 N—Y—NH—CO— radical, an R 2 -A-CO—NH—Y—NH—CO— radical or an R 3 Si—(O—SiR 2 ) n —X-A-CO—NH—Y—NH—CO— radical, R 2 are the same or different and are a monovalent, optionally silyl-substituted hydrocarbyl radical, A′ are the same or different and has a definition given for A, Z are the same or different and are monovalent, optionally substituted hydrocarbyl radicals or monovalent organosilicon radicals, Y′ are the same or different and has a definition given for Y, E are the same or different and are divalent, optionally substituted hydrocarbyl radicals, n is an integer from 1 to 4000, a is an integer of at least 1, b is an integer from 0 to 40, c is an integer of at least 1 and d is an integer from 0 to 5, with the proviso that, in compound of the formula (1), the a blocks and b blocks may be randomly distributed in the polymer.
