Absorbable block copolymers and surgical articles fabricated therefrom

摘要

Block copolymers have one of the block made from hard phase forming monomers and another block made from soft phase forming monomers copolymerized with randomly intermingled units of other soft phase forming monomers. Particularly useful copolymers are initiated with a polyalkylene oxide initiator. The copolymers are useful in forming surgical articles, including both monofilament and multifilament sutures.
