| abstract |
The present invention is directed to crystalline, absorbable block/segmented copolymers which are the reaction product of a linear prepolymer which is a polytrimethylene dicarboxylate of succinic, glutaric, or adipic acid and either glycolide, 1-lactide, or mixtures thereof. Preferably the prepolymer is preliminarily end-grafted with a further monomer such as trimethylene carbonate or epsi-caprolactone. The crystalline copolymers of this invention are tailored for fabrication into several forms of absorbable biomedical devices including monofilament sutures. |
