Progress in development of catalyst systems for coordinated polymerization of olefins Ⅰ. The major catalyst component

从构成催化剂体系的金属中心原子出发,介绍了烯烃配位聚合催化剂体系的主催化剂组分的发展历史和最新研究动态,重点讨论了烯烃配位聚合催化剂发展过程中典型催化剂的结构特征和催化聚合性能,包括典型的Ziegler-Natta催化剂,茂金属催化剂和非茂金属催化剂。其中,以第ⅣB族过渡金属为中心的催化剂种类和数量最多,占据了整个烯烃聚合催化剂的绝大部分,并且对我国烯烃聚合催化剂的研究与开发方向提出了建议。

Proceeding from the central metal atom contained in the catalyst system, this paper reviewed the main achievements and current development status of the major components in the catalyst system for coordinated polymerization of olefins. The structural character and polymerization reactivity of the typical catalysts were emphatically discussed, involving Ziegler-Natta catalysts, metallocene and non-metallocene catalysts. The catalysts based on ⅣB transition metal atom had the most variety and amount of their kindred, constituted the majority of the catalyst system for olefin polymerization. A suggestion was set forth for the research and development of olefin polymerization catalysts in China.
