Abstract
The present invention is directed to crystalline copolymers of l-lactide and a minor portion of a cyclic monomer, preferably .epsilon.-caprolactone or trimethylene carbonate or both. The present copolymers have a melting temperature of at least 150.degree. C. and a crystallinity of at least 20%. Preferred are high molecular weight copolymers having an inherent viscosity of at least 1.1 dl/g. A variety of surgical constructs may be formed from the present copolymers. Surgical sutures made of mono- or multifilament yams of the present copolymers will bioabsorb in less than three years and will maintain at least 50% of their initial strength three weeks post-operatively.
