乙醇酸和DL─乳酸交替共聚物的合成和表征

Synthesis and Characterization of Alternating Copolymer of DL-Lactic Acid and Glycolic Acid

摘要: 乙醇酸和ＤＬ－乳酸交替共聚物具有不同于其无规共聚物的理化性能和生物降解性。以ＤＬ－３－甲基－１，４－二烷－２，５－二酮为单体，通过在辛酸亚锡引发下的本体开环聚合，合成了该交替共聚物，并进行了结构表征。

Abstract: n alternating copolymer of DL-lactic acid and glycolic acid was synthesized by ring-opening polymerization of DL-3-methyl-1,4-dioxane-2,5-dione upon initiation with an appropriate amount of stannous octoate.The polymer was characterized by 1H-/13C -NMR, D
