摘　　要：介绍了Z ieg ler-Natta丙烯聚合催化剂体系中内给电子体的研究进展,对现有的内给电子体进行简单的分类,探讨了含有不同取代基的同类化合物作为内给电子体对催化剂的活性和α-烯烃聚合物等规度的影响,并对Z ieg ler-Natta丙烯聚合催化剂体系中内给电子体的进一步研究提出了看法。Development of various kinds of internal electron donors in Ziegler-Natta catalysts for propylene polymerization was introduced. The donors were simply classified and comparison of their experimental results was carried out. Effects of different substituent groups of donors on catalytic activity of catalyst and isotacticity of α-olefin polymer were discussed. Some views on further research of internal donors were proposed.
