This invention provides various copolymers comprising a repeating unit of the chemical formula: (CH.sub.2 CH.sub.2 CH.sub.2 OCH.sub.2 CO.sub.2) and other repeating units having a chemical formula selected from the group consisting of: (CHRCO.sub.2), ([CH.sub.2 ].sub.5 CO.sub.2), (CH.sub.2 CH.sub.2 OCH.sub.2 CO.sub.2), (CH.sub.2 CH.sub.2 CH.sub.2 OCO.sub.2), and combinations of two or mope thereof wherein R is a hydrogen atom or a methyl group and the first repeating unit is less than 45 weight percent of the total weight of the copolymer. This invention also relates to use of these copolymers in the fabrication of absorbable surgical devices such as sutures and as coatings for medical devices.
本发明提供了一种包含化学式重复单元(CH.sub.2 CH.sub.2 CH.sub.2 OCH.sub.2 CO.sub.2)和其他化学式重复单元的各种共聚物,所述化学式重复单元从以下组中选择:(CHRCO.sub.2)、([CH.sub.2].sub.5 CO.sub.2)、(CH.sub.2 CH.sub.2 OCH.sub.2 CO.sub.2)、(CH.sub.2 CH.sub.2 CH.sub.2 OCO.sub.2)以及两种或更多的组合,其中R是氢原子或甲基基团,且第一个重复单元的重量百分比小于共聚物的总重量的45%。本发明还涉及将这些共聚物用于制造可吸收的外科器械,例如缝合线,并用作医疗器械的涂层。
