Title:
CATALYSTS FOR OLEFIN POLYMERIZATION OR OLIGOMERIZATION
Document Type and Number:
WIPO Patent Application WO2006010065
Kind Code:
A3
Abstract:
Novel iron and cobalt complexes of certain novel tricyclic ligands containing a "pyridine" ring and substituted with two imino groups are po-lymerization and/or oligomerization catalysts for olefins, especially ethyl-ene. Depending on the exact structure of the ligand, and polymerization process conditions, products ranging from a-olefins to high polymers may be produced. The polymers, especially polyethylenes, are useful for films and as molding resins.
