聚丙烯催化剂中含氮原子给电子体化合物的研究进展

Development of catalyst with compounds containing nitrogen as internal electron donor for propylene polymerization

综合介绍了近年来聚丙烯催化剂中含氮原子类给电子体化合物的研发进展情况,讨论了不同结构的含氮原子化合物作为内、外给电子体时用于丙烯聚合时的性能,对含氮原子结构化合物的催化剂与邻苯二甲酸酯类催化剂进行了比较,展望了聚丙烯催化剂中含氮原子内外给电子体的未来发展情况。

Development of research on the electron donor containing nitrogen group used in the propylene polymerization was reviewed. Performance of catalysts with this kind of compounds as internal or external electron donor was involved according to the compound structure. Characteristics of catalysts prepared with nitrogen-containing compounds as internal donor was compared with that of catalysts using phthalates as internal electron donor. Catalysts are more challenging and are outlined. Future application of electron donor containing nitrogen groups in catalysts for polypropylene polymerization is prospected.
