DI- AND TRI-HETEROATOM SUBSTITUTED INDENYL METAL COMPLEXES

摘要

Novel metal complexes containing at least two heteroatoms attached to an indenyl or substituted indenyl radical which is bridged by ligand group thereby forming a covalent or coordinate/covalent bond to the metal, the use of such metal complexes in the formation of polymerization catalysts and processes for polymerizing alpha -olefins using such catalysts.
