摘　　要：综述了酯交换法合成聚碳酸酯二醇(PCDL)的研究进展。通过对碳酸二甲酯、碳酸二乙酯、碳酸乙烯酯、碳酸二苯酯等用于酯交换合成PCDL进行了比较,指出碳酸二苯酯与二元醇合成PCDL是最具工业化前景的方法。对碱金属化合物、有机金属化合物、有机胺类化合物、Mg/Al水滑石、负载型催化剂、酶等催化剂的催化性能作了评述。Latest researches on synthesis of polycarbonate diols via transesterification were reviewed.By comparison of dimethyl carbonate,diethyl carbonate,ethylene carbonate and diphenyl carbonate used in synthesis of polycarbonate diols,it was founded that preparation of polycarbonate diols with diphenyl carbonate and diol was the most suitable route for commercialization.The catalytic properties of alkali metal compounds,organometallic compounds,organic amines,Mg/Al hydrotalcite,supported catalyst and enzyme were discussed.
