以可溶性淀粉、乳酸、乙醇酸和己内酰胺为原料在氯化亚锡催化下直接缩聚制备得到了淀粉接枝乳酸-乙醇酸共聚物及淀粉接枝乳酸-乙醇酸-己内酰胺共聚物。用核磁共振(NMR)、差热(DSC)及热重(TG)分析分别对产物的结构和热性能进行了表征。
Starch-grafted lactic acid-glycolic acid copolymer and starch-grafted lactic acid-glycolic acid-caprolactam copolymer were prepared by direct polycondensation of soluble starch, lactic acid, glycolic acid and caprolactam catalyzed by stannous chloride. The structure and thermal properties of the products were characterized by NMR, DSC and TG respectively.
