茂金属催化剂及其聚烯烃的开发

Development of Metallocene-based Catalysts and Their Polyolefines

报导了中国石油化工总公司石油化工科学研究院近两年茂金属催化剂及其催化烯烃聚合技术的研究进展。间规选择性复合型茂金属催化剂技术已开发成功;用其催化丙烯聚合,在国内首次得到合格的商业用间规聚丙烯;完成了限制几何构型复合型茂金属的合成探索,获得具有较好活性的系列催化剂;实现了茂金属催化剂的负载化,为茂金属催化剂在气相烯烃聚合工艺中的应用奠定了基础。

The latest studies and developments on metallocene -based catalysts and polyolefines in RIPP have been reported in this paper. The research achievements such as syndiospecific metallocene catalyst technology, syndiotactic polypropylene, synthesis of constrained geometry metallocene catalyst and preparation of supported metallocenes, etc. have been emphatically described.
