    摘要： Block copolymers wherein the first block contains from about 20 to about 80 mole percent of repeating units derived from lactide randomly combined with from about 20 to 80 mole percent of repeating units derived from glycolide and the second block contains repeating units derived from lactide and repeating units derived from other bioabsorbable monomeric units, such as glycolide, the second block containing a higher proportion of repeating units derived from lactide than the first block, with units derived from lactide constituting from about 40 to about 90 mole percent of the entire block copolymer are useful in forming surgical articles, including sutures.

    摘要翻译： 嵌段共聚物，其中第一嵌段含有约20至约80摩尔％的衍生自丙交酯的重复单元与约20至80摩尔％的衍生自乙交酯的重复单元随机组合，第二嵌段含有衍生自丙交酯和重复单元的重复单元 衍生自其它生物可吸收单体单元如乙交酯，第二嵌段含有比第一嵌段衍生自丙交酯的更高比例的重复单元，衍生自构成整个嵌段共聚物的约40至约90摩尔％的丙交酯的单元是有用的 在形成外科用品时，包括缝线。
