Title: HOMOGENEOUS GROUP IVB METALLOCENE-BASED CATALYSTS OF OLEFINS POLYMERIZATION
Abstract: Metallocene based polymerization catalysts have been the most impetus in the field of olefins polymerization in recently years. In contrast to heterogeneous Ziegler Natta catalyst system, polymerization by a homogeneoas metallocene based catalyst occurs principally at a single type of metal center with a defined coordination environment. This makes it possible to correlate metallocene structures with polymer′ properties such as molecular weight, stereochemical microstructure, mechanical properties and so on. The types of metallocene based catalysts in the last twenty years, the connection between catalyst′s microstructure and catalyst′s stereoselectivity and the synthesis of metallocene based catalysts were reviewed.
