聚丙烯催化剂内给电子体研究进展

Research progress of internal electron donors in polypropylene catalysts

丙烯聚合用Ziegler-Natta催化剂的进步离不开内给电子体的发展,本文简述了内给电子体作用机理的研究进展,回溯了Ziegler-Natta催化剂内给电子体由单酯类、二酯类到二醚类以及二醇酯类的发展过程,介绍了不同内给电子体的特性以及内给电子体的最新研究进展。并对未来内给电子体的发展趋势进行了展望。

The progress of Ziegler-Natta catalysts for propylene polymerization cannot be separated from the development of internal electron donors.This paper briefly describes the research progress of the mechanism of internal electron donors,and reviews the development process of the internal electron donors in Ziegler-Natta catalyst from monoesters,diesters to diethers and diol esters.The properties of different internal electron donors and the latest research progress of internal electron donors are introduced.The future development trend of internal electron donor is prospected.
