Abstract:
1. A water-soluble copolymer of formula (I): wherein X and Y are group (a), unless X is an endcap, in which case X is L—O and L is an organic group, or unless Y is an endcap, in which case Y is a reactive or unreactive terminator group: wherein r of group (a) for each group X and Y are independent values from each other, and wherein Q and R are a group represented by formula (I) in which m for each group Q and R are independent values from each other, but if R is an endcap, then R is a reactive or unreactive terminator group, or if Q is an endcap, then Q is L—O and L is an organic group; R r is an integer in the range of 0 to 5,000; b is an integer in the range of 1 to 50; R Z is selected from the group consisting of NR in which R 6 , R 7 , and R 8 are the same or different C 1-6 alkyl groups, R 9 is a tri(C 1-6 alkyl) silyl group, and B is a C 1-6 alkyl group; and m is a positive number of 1 to 5,000.
