Abstract

The present invention is directed to certain novel late transition metal salicylaldimine chelates and, further, to novel bidentate ligand compounds of substituted salicylaldimine, and their utility as polymerization catalysts alone or in combination with adjunct agent and/or Lewis base in processes of polymerizing olefin monomers and copolymerizing olefin monomers with functionalized olefin monomers.
