摘　　要：利用戊二酸锌(ZnGA)催化衣康酸酐(IAn)和环氧丙烷(PO)共聚合制备聚酯,采用FT-IR和~1HNMR对聚合物结构进行了表征.考察了聚合反应温度、反应时间、单体摩尔比和催化剂浓度对共聚合反应的影响.结果表明,ZnGA能够有效催化IAn与PO共聚,共聚合反应中交联现象明显.优化聚合反应条件,确定最佳条件为:反应温度为100℃,时间为96h,单体摩尔比为1∶1,催化剂浓度为0.01g·mL^(-1).T he copolymerization of itaconic anhydride and propylene oxide to yield aliphatic polyester has been achieved through the use of zinc glutarate . The structure of copolymers is characterized by FT‐IR and 1 HNMR . The copolymerization conditions including reaction temperature , reaction time , monomer molar ratio and catalyst concentration are investigated in detail . It has found that the obvious cross‐linking in the copolymerization of itaconic anhydride and propylene is oxided owing to the high activity of exo‐type double bond of itaconic anhydride . The results showed that the optimum reaction conditions are as follows ：temperature 100 ℃ ,time 96 h ,monomer molar ratio 1∶1 ,catalyst concentration 0.01 g-mL -1 .
