国内丙烯聚合催化剂给电子体的研究进展

Domestic Development on Donor of Polypropylene Catalyst

内外给电子体在提高聚丙烯催化剂活性及控制产品等规度和其他性能中都有着极为重要的作用。文章简述了聚丙烯催化剂中给电子体的研究发展历史,以及国内聚丙烯催化剂及其内外给电子体的研究、生产现状。

Both internal donor and external donor play a very important role on the catalyst activity, products＇ isotacticity and other properties. The article introduces briefly the development of donor in polypropylene catalyst system, domestic research and manufacture on catalyst/internal donor/external donor.
