Patent ID: 8664426

Claim:
A polymer formed by polymerizing a compound selected from: with a compound selected from a dicarboxylic acid, a dialcohol, a diisocyanate, an amino-alcohol, a hydroxycarboxylic acid, and a diamine to form a polymer selected from a polyester, polyurethane, polyesteramide, polyamide, and polyanhydride; wherein: X is selected from: —CH 2 COO—; —CH(CH 3 )COO—; —CH 2 CH 2 OCH 2 COO—; —CH 2 CH 2 CH 2 CH 2 CH 2 COO—; —(CH 2 ) y COO—; and, —(CH 2 CH 2 O) z CH 2 COO—, where y is selected from 2,3,4 and 6-24 and z is selected from 2-24, Y is selected from: —COCH 2 O—; —COCH(CH 3 )O—; —COCH 2 OCH 2 CH 2 O—; —COCH 2 CH 2 CH 2 CH 2 CH 2 O—; —CO(CH 2 ) m O—; and, —COCH 2 O(CH 2 CH 2 O) n —, where m is selected from 2-4 and 6-24 and n is selected from 2-24; R′ is selected from hydrogen, benzyl, and a straight-chained or branched C 1-6 alkyl; a, b, and c, are independently selected from 0-4, provided that a+b+c total from 2-4; and, alternatively, when 1 or 2 of a, b, and c are 0, then “O—(X) b ” is NR′; and, alternatively, when 1 or 2 of a, b, c are 0, then “(Y) c ” is C(O), further provided that when “(Y)” is C(O), then R′ is other than H.
