Abstract
Polymer blends of glycolide and/or lactide homopolymer and/or glycolide/lactide copolymer and polycaprolactone and/or polytrimethylene carbonate homopolymer or copolymers thereof and absorbable surgical devices manufactured therefrom having improved mechanical properties, such as improved impact resistance and improved cyclic flex, are disclosed. The blends may be prepared by polymerizing a glycolide or lactide containing polymer in the presence of a polymer derived from trimethylene carbonate or .epsilon.-caprolactone.
