Patent ID: 8628761

Claim:
A biodegradable, biocompatible polyurethane/urea polymer composition comprising the reaction product of: a) a flowable prepolymer comprising the reaction product of: i) one or more isocyanates; and ii) one or more multifunctional core molecules having a molecular weight of 400 or less and having at least two functional groups that react with said isocyanate thereby forming urethane or urea groups; and b) one or more soft segment-forming functional oligomers selected from the group consisting of: i) linear oligomers; ii) star oligomers; iii) dendrimeric oligomers; and iv) hyperbranched oligomers; wherein the functional oligomer has degradable arms comprising one or more ester functionalities; and wherein the flowable prepolymer is curable with the functional oligomer at 30° C.
