Patent ID: 7622544

Claim:
A process of producing a polymer comprising: (a) providing hydroxyl-carboxyl protomers; and (b) condensing said hydroxyl-carboxyl protomers to form at least one bond A-B, thereby producing the polymer, wherein: A is selected from the group of radicals consisting of: (NHX)(COY)CH—(CH 2 ) 3 —NH—C(═NH)O. (NHX)(COY)CH—(CH 2 ) 4 O. (NHX)(COY)CH—CH 2 O. (NHX)(COY)CH—CHCH 3 O. and (NHX)(COY)CH—CH 2 —C 6 H 4 p-O., and B is selected from the group of radicals consisting of (NHW)(COZ)CH—CH 2 —C(═O). (NHW)(COZ)CH—(CH 2 ) 2 —C(═O). and WNHCHR B C(═O). wherein R B is selected from the group consisting of: —(CH 2 ) 3 —NH—C(NH 2 )(═NH), —(CH 2 ) 3 —NH—C(OH)(═NH), —(CH 2 ) 4 NH 2 , —(CH 2 ) 4 OH, —CH 2 OH, —CHOHCH 3 , —CH 2 —C 6 H 4 p-OH, —CH 2 CONH 2 , —CH 2 COOH, —(CH 2 ) 2 CONH 2 , —(CH 2 ) 2 COOH, —CH 2 SH, —H, —CH 3 , —CH 2 c(C═CH—N═CH—NH—), —CH(CH 3 )CH 2 CH 3 , —CH 2 CH(CH 3 ) 2 , —(CH 2 ) 2 SCH 3 , —CH 2 C 6 H 5 , —CH 2 -c(C═CH—NH-Ph-) and —CH(CH 3 ) 2 , wherein Y and Z are independently selected from the group consisting of OH and a proteinaceous material; and wherein W and X, are independently selected from the group consisting of H and a proteinaceous material; and wherein bond A-B is an ester bond.
