Patent ID: 8343472

Claim:
A biodegradable, biocompatible polyurethane/urea polymer composition comprising the reaction product of: a) a flowable prepolymer comprising the reaction product of: i) an isocyanate; and ii) a low molecular weight multifunctional core molecule having a molecular weight of 400 or less and at least two functional groups that react with said isocyanate thereby forming urethane or urea groups; and b) a soft segment-forming functional oligomer chosen from: i) linear oligomers; ii) star oligomers; iii) dendrimeric oligomers; and iv) hyperbranched oligomers; wherein the functional oligomer has degradable arms and is selected from the group consisting of lactides, glycolides, lactide/glycolides, caprolactones, propylene fumarates, glycolic acid, dioxanones, anhydrides, polyorthoesters and phosphorylacholines; and wherein the flowable prepolymer is curable with the functional oligomer at 30° C.
