LATE TRANSITION METAL CATALYSTS FOR OLEFIN POLYMERIZATION AND OLIGOMERIZATION

WIPO Patent Application WO2004007509

A8

This invention relates to a transition metal compound represented by the formula LMX wherein M is a Group 3 to 11 metal L is a bulky bidentate or tridentate neutral ligand that is bonded to M by two or three heteroatoms and at least one heteroatom is nitrogen; X is a substituted or unsubstituted catecholate ligand provided that the substituted catecholate ligand does not contain a 1,2-diketone functionality.

JP4123881	Transition metal compounds, coordinating compounds, catalysts for olefin polymerization, and methods for producing polyolefins using them.
WO/2004/101634	OLEFIN POLYMERIZATION CATALYST SYSTEM USEFUL FOR POLAR MONOMERS
