Abstract:
1. A polymer comprising: (a) at least one monomer unit having the Formula wherein m is 0, 1, or 2; Y is -OMe or -OEt; and A is selected from the group consisting of —CO—, —C(═NH)—, and —CO—X—CO—, where X is selected from the group consisting of C 1 -C 18 alkylene, C 1 -C 18 alkenylene, divalent C 6 -C 10 arylene, divalent C 7 -C 18 alkylaryl, CH 2 OCH 2 , CH 2 O(CH 2 CH 2 O) s CH 2 , (CH 2 ) r CO 2 (CH 2 CH 2 CH 2 O) s CO(CH 2 ) r , and (CH 2 ) r CO 2 (CH 2 CH 2 O) s CO(CH 2 ) r , where r is 2 to 4 and s is 1 to 5000; and (b) at least one monomer unit having the Formula wherein m is 0, 1, or 2; Y is —OH or —O-benzyl; and A is selected from the group consisting of —CO—, —C(═NH)—, and —CO—X—CO—, where X is selected from the group consisting of C 1 -C 18 alkylene, C 1 -C 18 alkenylene, divalent C 6 -C 10 arylene, divalent C 7 -C 18 alkylaryl, CH 2 OCH 2 , CH 2 O(CH 2 CH 2 O) s CH 2 , (CH 2 ) r CO 2 (CH 2 CH 2 CH 2 O) s CO(CH 2 ) r , and (CH 2 ) r CO 2 (CH 2 CH 2 O) s CO(CH 2 ) r , where r is 2 to 4 and s is 1 to 5000.
