Abstract
Absorbable binary and tertiary blends of homopolymers and copolymers of poly(lactide), poly(glycolide), poly(.epsilon.-caprolactone), and poly(p-dioxanone) are described. The blends when used to manufacture medical devices exhibit shape retention, dimensional stability and palpability without loss of the strength, stiffness and BSR found for poly(lactide) homopolyers and/or poly(lactide-co-glycolide) copolymers.
