Abstract: Catalyst compositions comprising Group 4 metal complexes containing a diene moiety and activating cocatalysts are used as catalysts for polymerizing olefins, diolefins and/or acetylenically unsaturated monomers. Vinylidene aromatic monomers, particularly styrene are polymerized to form highly syndiotactic polymers.
