Abstract
Novel compounds are provided that are useful as catalysts, particularly in the polymerization of addition polymerizable monomers such as olefinic or vinyl monomers. The compounds are multinuclear complexes of transition metals coordinated to at least one unsaturated nitrogenous ligand. Catalyst systems containing the novel compounds in combination with a catalyst activator are provided as well, as are methods of using the novel compounds in the preparation of polyolefins.
