摘　　要：根据锌、镁及钙金属络合物不同配体的结构特点,综述了近年来锌、镁及钙金属络合物用于催化丙交酯开环聚合的研究进展,以及影响催化剂活性和立体选择性的主要因素。锌、镁及钙金属络合物具有生物相容性,作为催化剂使用时,对环境友好,且在催化丙交酯开环聚合中表现出很高的活性以及很好的立体可控选择性,但该类催化剂对空气及水敏感,需要无水无氧条件下才能催化丙交酯聚合,影响了其应用。因此,研究催化剂的结构特点、开发活性高且对空气敏感程度低的催化剂十分必要。The recent advances of zinc, magnesium and calcium metal complexes for lactide ring-opening polymerization were summarized according to the structure characters of various ligands around the metals, and the main factors affecting the activity and stereoselectivity of the catalysts were analyzed. The zinc, magnesium and calcium metal complexes had not only good biocompatible and environmentally friendly properties, but also high activity and excellent stereocontrolled selectivity in lactide ring-opening polymerization. But the catalysts were sensitive to air and water, so the lactide ring-opening polymerization must be performed without water and air, and these limited the applications of the calalysts. So it is necessary to study the structure characters of the catalysts and develop the catalysts with high activity and low sensitivity to air.
