Claim:
A polymer, comprising: a first repeating unit, which is a difunctionalized aromatic of formula I: and a second repeating unit formed from a compound selected from a dicarboxylic acid, a dialcohol, a diisocyanate, an amino-alcohol, a hydroxycarboxylic acid, and a diamine; wherein: Ar is an aromatic ring substituted with 1, 2, or 3 R groups; X is independently at each occurrence 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 CO O—; —(CH 2 ) y COO—; and, —(CH 2 CH 2 O) z CH 2 COO—, where y is independently selected from 2, 3, 4 and 6-24 and z is independently selected from 2-24; Y is independently at each occurrence 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 C 1-6 alkyl; p and q are independently selected from 0, 1, 2, 3, and 4, provided that p+q total 2, 3, or 4; a and b are independently selected from 0, 1, 2, 3, and 4, provided that a+b total from 1, 2, 3, 4, 5, or 6; R is independently selected from —O— (X) c —R′ and —O—(Y) c —R′; c is independently selected from 0, 1, 2, 3, and 4; alternatively, R is independently selected from H, ═O, O-glycosides, —(CH 2 ) 0-2 —OR a , —(CH 2 ) 0-2 —C 6 H 5 , —(CH 2 ) 0-2 —CHO, Cl, F, Br, I, —(CH 2 ) 0-2 —OC(O)—R a , —(CH 2 ) 0-2 —CO 2 —R a , —(C(CH 3 )) 0-2 —CO 2 —R a , —(CH 2 ) 1-2 CO 2 —(CH 2 ) 1-2 —CO 2 —R a , —(C(CH 3 )) 1-2 —CO 2 —(CH 2 ) 1-2 —CO 2 —R a , —(CH 2 ) 0-2 —CO—R a , —O(CH 2 ) 0-2 —C 6 H 5 , —O(CH 2 ) 1-2 —CO 2 —R a , —O(C(CH 3 )) 1-2 —CO 2 —R a , —O(CH 2 ) 1-2 —CO—R a , —(CH 2 ) 0-2 —NO 2 , —(CH 2 ) 0-2 NR a R a , —(CH 2 ) 0-2 —NR a COR a , —(CH 2 ) 1-2 —NR a C(O)(CH 2 ) 1-2 OR a , —C 6 H 5 , —C 6 H 5 OR a , and —C 6 H 5 —CH═CHCO 2 R a ; and, R a is independently selected from H and C 1-6 alkyl.
