Patent ID: 7041767

Claim:
Polysiloxane polymers having the repeating units wherein X is a divalent hydrocarbon radical with at least 4 carbon atoms, which contains a hydroxyl group and which carbon atoms optionally are interrupted by an oxygen atom, and wherein the X groups are the same or different in the repeating units, Y is a divalent hydrocarbon radical having at least 2 carbon atoms, which optionally comprises a hydroxyl group and in which the carbon atoms are optionally interrupted by one or more oxygen or nitrogen atoms, R 1 , R 2 , R 3 and R 4 are the same or different and represent alkyl groups of 1 to 4 carbon atoms or benzyl groups, or the R 1 and R 3 radicals or the R 2 and R 4 together form a bridging alkylene radical, R 6 is H or an alkyl radical having 1 to 20 carbon atoms, which is optionally oxygen-substituted, E is the structure —B—O—(CH 2 CH 2 O) v (CH 2 CHCH 3 O) w B—, wherein B represents straight chain or branched chain C 2 to C 6 alkylene, v is a number from 0 to 200, w is a number from 0 to 200, v+w≧1, n represents a number from 2 to 1000, wherein the n's in the repeating units may be the same or different, and A − represents an inorganic or organic anion.
