ABSTRACT:
Metal-ligand complexes that are useful as precursors to catalysts for the polymerization of olefins are provided. Certain of the catalysts are particularly effective at polymerizing ethylene and styrene into copolymers having novel properties, including a low molecular weight and close comparison between vinyl and methyl end groups.
