摘　　要：叙述了近年来氯化镁负载单中心催化剂的新进展,包括用氯化镁负载茂金属催化剂和后过渡金属催化剂的负载化方法以及在烯烃聚合的应用。所形成的氯化镁负载催化剂既能保持均相催化剂的高活性,满足工业生产要求,同时也较均相催化剂有着诸多优势,可改善聚合物的形态结构,抑制粘釜现象等。指出了氯化镁负载单中心催化剂未来研究的方向。Recently progress on MgCl2 supported single-site catalysts for olefins polymerization was reviewed including the preparation method of MgCl2 supported metallocene catalysts and late transition metal catalysts and the application in olefin polymerization.The MgCl2 supported catalyst can maintain the high activity of homogeneous catalysts and meet the requirements of industrial production.It has many advantages over homogeneous catalysts.For example,it can improve the polymer morphology,and stop the phenomenon of sticky kettle.This paper points out the future research directions of the MgCl2 supported single-site catalysts.
