Claim:
A polymer comprising a recurring unit of the formula (I) and a recurring unit of the formula (II): wherein: T and E are each independently a first optionally substituted hydrocarbyl radical comprising from about 2 to about 40 carbons; Q is a second optionally substituted hydrocarbyl radical comprising from about 1 to about 20 carbons; A 1 and A 2 are each independently a direct bond or an organic connecting group comprising from about 1 to about 20 carbons; R″=H, optionally substituted C 1 -C 20 alkyl, optionally substituted C 6 -C 12 aryl, optionally substituted C 7 -C 20 aralkyl, optionally substituted C 2 -C 20 alkenyl, Group I metal ion, Group II metal ion, or NR 1 4 , where each R 1 is independently selected from H, optionally substituted C 1 -C 20 alkyl, optionally substituted C 6 -C 12 aryl, optionally substituted C 7 -C 20 aralkyl, and optionally substituted C 2 -C 20 alkenyl; and the polymer has a weight average molecular weight of at least about 500; wherein the organic connecting groups A 1 and A 2 are each independently represented by -A 3 -A 4 -A 5 -A 6 -, where: A 3 =a direct bond, NR′ or O, where R′ is H or C 1-3 alkyl; A 4 =a direct bond, C═O, optionally substituted C 1 -C 10 alkylene, or optionally substituted C 6 -C 12 aryl; A 5 =a direct bond, O, NR′″, amide, urethane or urea, where R′″ is H or C 1-3 alkyl; and A 6 =a direct bond, O, optionally substituted C 1 -C 20 alkyl, optionally substituted C 2 -C 20 alkenyl or optionally substituted C 7 -C 20 aralkyl; further wherein at least one of the organic connecting groups A 1 and A 2 is —CH 2 —CH(OH)—CH 2 —O— with a first proviso that Q does not contain a Si(OR″) 3 group; and with a second proviso that A 2 is not unsubstituted —C(═O)-alkyl.
