摘要：
Block copolymers wherein one of the blocks is made from hard phase forming monomers and another of the blocks is made from soft phase forming monomers copolymerized with randomly intermingled units of other soft phase forming monomers. The copolymers are useful in forming surgical articles, including both monofilament and multifilament sutures. The block copolymer preferably comprising:a) a proportion of glycolic acid ester units as end blocks, andb) a center block comprising 1,4 dioxan-2-one randomly polymerized with 1,3 dioxane-2-one.
