摘　　要：以非对称NNO三齿叔胺配体与无水氯化钙为原料,制得金属配合物(Ca L).测定了该金属配合物催化剂催化丙交酯开环聚合反应的性能.聚合反应的可控性研究表明,数均分子量与单体转化率之间呈线性关系,说明这种配合物能够催化丙交酯活性可控开环聚合.反应动力学研究结果表明,聚合反应符合一级动力学.The metal complex catalyst(CaL)was prepared from an unsymmetric tridentate NNO tertiary amine ligand and anhydrous calcium chloride.The performance of metal complex catalyst for the ring-opening polymerization of lactide was tested.The study on the controllability of polymerization showed that there was a linear relationship between the number average molecular weight and the monomer conversion,implying that this complex could catalyze the living and controlled ring-opening polymerization of lactide.The results of reaction kinetics indicated that the polymerization followed first-order kinetics.
