【摘要】 利用戊二酸锌（ZnGA）催化制备二氧化碳（CO₂）、环氧丙烷（PO）和降冰片烯二酸酐（EA）三元共聚物,得到了一种新型的脂肪族聚碳酸酯（PPCEA）,产物产率高。利用核磁共振氢谱（¹H NMR）和凝胶渗透色谱（GPC）表征了聚合物结构。研究结果表明,戊二酸锌能够有效催化CO₂、PO和EA三元共聚合反应,所得三元共聚物PPCEA相比于聚碳酸亚丙酯（PPC）具有高的热性能、力学性能和降解性能。更多还原

【Abstract】 Terpolymerization of carbon dioxide（CO₂）,propylene oxicle（PO） and endic anhydride（EA） was successfully carried out using zinc glutarate（ZnGA） as catalyst,consequently giving a new type of polycarbonate（PPCEA） in high yield.The resulting terpolymers were fully characterized by¹ H NMR and GPC techniques.The results showed that zinc glutarate could catalyze the terpolymerization of CO₂,PO,EA effectively;and PPCEAs exhibited superior thermal,mechanical performance and high degradability compared with PPC.更多还原
