Abstract:
1. A process for the polymerization of one or more monomers consisting of olefins and functional group containing olefins, comprising the step of contacting, at a temperature of about −100° C. to about +200° C., said one or more monomers with a catalyst composition comprising a transition metal and a bidentate ligand coordinated in a square planar configuration, wherein the ligand and the transition metal are coordinated through two different nitrogen atoms, or through a nitrogen atom and a phosphorous atom, the coordinated nitrogen atoms and phosphorous atoms being part of the ligand, and wherein the ligand has sufficient steric bulk on both sides of the coordination plane to permit formation of a polymer of said one or more olefins with a degree of polymerization of at least about 10 or more.
