Title: Polymerization catalyst and process

Abstract: A catalyst is provided for addition polymerization of olefinically unsaturated monomers comprising a first compound MY, wherein M is a transition metal in a low valency state or a transition metal in a low valency state coordinated to at least one coordinating non-charged ligand, Y is a monovalent, divalent or polyvalent counterion; an initiator compound comprising a homolytically breakable bond with a halogen atom; and an organodiimine, where at least one of the nitrogens of the diimine is not part of an aromatic ring. A catalyst for addition polymerization of olefinically unsaturated monomers is also provided comprising a first component of Formula wherein M=a transition metal of low valency state, L=an organodiimine where at least one of the nitrogens of the diimine is not part of an aromatic ring, A=an anion, n=an integer of 1 to 3, m=an integer of 1 or 2; e) An initiator compound comprising a homolytically breakable bond with a halogen atom. Preferably, the organodiimine is a 1,4-diaza-1,3-butadiene, a pyridine carbaldelyde imine, an oxazolidone or a quinoline carbaldehyde. Processes for using the catalysts are also disclosed.
