摘要：

本发明提供一种用于制备具有均匀有序分布的酯族聚酯的可吸收链段嵌段共聚物的方法,包括至少两种脂族聚酯单体的共聚,其中一种单体在共聚条件下酯交换形成链段嵌段共聚物;然后通过冷却链段嵌段共聚物到在少于60分钟发生酯交换的温度以下使共聚骤冷. The present invention provides a process for producing aliphatic polyesters having a uniform and orderly distribution of absorbable segmented block copolymer method, comprising copolymerizing at least two aliphatic polyester monomers wherein one monomer copolymerizable segmented block copolymer is formed under transesterification conditions; and then by cooling the segmented block copolymer to occur in less than 60 minutes following temperature transesterification copolymerization quenched.
