烯烃聚合高性能FI催化剂的进展

Progress in High Performance FI Catalyst for Olefin Polymerizations

FI催化剂系一近几年发展起来的烯烃聚合高性能催化剂。以它的极高的活性、聚合物分子结构的可控性、多重活性聚合等特性而引人注目。本评述首先进行该催化剂的化学描述,然后分别介绍该催化剂的主要特征、活性中心结构、聚合机理和应用,重点介绍该催化剂的五大特征。

FI catalyst as a high performance catalyst is developed for olefin polymerization in recent years. The catalyst has attracted much attention, because of very high polymerization activity, structural control of polyolefins with facility, multiple living polymerization and so on. Chemical description of the catalyst is recounted first, and then five main characteristics with emphasis, structure of active species of the catalyst, polymerization mechanism, and application are presented respectively in the review with 5 Tables, 6 Schemes, 19 Figures, 25 Complexes, and 48 references.
