3-HETEROATOM SUBSTITUTED CYCLOPENTADIENYL-CONTAINING METAL COMPLEXES AND OLEFIN POLYMERIZATION PROCESS

摘要

PURPOSE: Heteroatom substituted cyclopentadienyl-containing ligands, metal complexes containing these ligands, and catalyst systems prepared from catalyst components comprising these metal complexes are provided. CONSTITUTION: The metal complexes contain a "a" heteroatom-Cp bond or a ring heteroatom-Cp bond in the 3-position of the Cp. In preferred metal complexes the ligand is a 3-heteroatom substituted indenyl group. The catalyst systems for olefin polymerization may be used at high temperatures, are highly active and produce high molecular weight polymer.
