Patent ID: 8883861

Claim:
In a biocompatible, bioresorbable polymer comprising a plurality of amide-containing monomeric repeating units, wherein the improvement comprises replacing at least 20 weight percent of the amide groups in said amide-containing monomeric repeating units with carbonyl-imine groups, and wherein said polymer is a heteropolymer or a copolymer characterized by one or more repeating units of the formula: wherein X 1 and X 2 are each independently selected from Br and I; y1 and y2 are each independently zero or an integer in the range of 1 to 4, and R 1 is selected from the group consisting of: wherein Z 4 is O or S; Z 5 is O or S; a and b independently range between 0 and 8, inclusive; and R 8 is selected from the group consisting of OH, a poly(alkylene oxide), O—(C 1 -C 18 alkyl), O-alkenyl O-alkynyl and O-cycloalkyl.
