Claim:
A polymer formed from polymerizing a functionalized diphenolic compound of formula I, II, or III: with a compound selected from a dicarboxvlic acid, a dialcohol, a diisocyanate, an amino-alcohol, a hydroxycarboxylic acid, or a diamine. wherein: R 1 is a bond or is selected from OCH 2 , OCH 2 CO 2 CH 2 , CO 2 CH 2 CO 2 CH 2 , CH 2 CHR 1a , CH 2 CHR 1a CO 2 CH 2 , CH 2 CHR 1a CO 2 CH 2 CO 2 CH 2 , CHâ•CH or (CH 2 ) d ; R 1a is selected from H and NRâ€²Râ€²; X is independently selected from: â€”CH 2 COOâ€”; â€”CH(CH 3 )COOâ€”; â€”CH 2 CH 2 OCH 2 COOâ€”; â€”CH 2 CH 2 CH 2 CH 2 CH 2 CO Oâ€”; â€”(CH 2 ) y COOâ€”; and, â€”(CH 2 CH 2 O) z CH 2 COOâ€”, where y is independently selected from 2-4 and 6-24 and z is selected from 2-24, Y is independently selected from: â€”COCH 2 Oâ€”; â€”COCH(CH 3 )Oâ€”; â€”COCH 2 OCH 2 CH 2 Oâ€”; â€”COCH 2 CH 2 CH 2 CH 2 CH 2 Oâ€”; â€”CO(CH 2 ) m Oâ€”; and, â€”COCH 2 O(CH 2 CH 2 O) n â€”, where m is selected from 2-4 and 6-24 and n is selected from 2-24; Râ€² is independently selected from hydrogen, benzyl, and C 1-6 alkyl; a, b, and c, are independently selected from 0-4, provided that a+b+c total from 1-6; d is selected from 1-8; and, e is selected from 0, 1, and 2.
