IVB金属配合物催化烯烃聚合的研究,不仅为工业界提供大量新型高效的催化剂模型,同时也为探索烯烃配位聚合机理提供了可能。更为重要的是,这些新型的配合物催化剂,可以制备具有优异性能的新型聚烯烃树脂。研究的核心仍然是新型聚烯烃催化剂,基于配合物中配位原子种类的不同,将催化剂的种类分为氮配位和氧配位催化剂。文中综述了近年来IVB金属配合物作为烯烃聚合催化剂的研究进展,集中讨论催化剂结构的变化对催化性能的影响。
The group IVB metal complexes as catalysts for olefin polymerization have provided various catalyst models ; meanwhile they provided the potentials in studying the mechanism of olefin polymerization. In addition, these complexes catalysts produced novel polyolefins with advanced properties. The IVB complexes were in two main families according to the donor supplied by the ligands with donor of N 0 atoms. The latestprogress of IVB metal complexes for olefin polymerization has been reviewed, which mainly focused on the correlation between complex structures and their catalytic performances.
