New metallocene compounds are described where the ligand contains at least one open-pentadienyl containing radical characterized by a cyclic or acyclic, six pi electron, delocalized, five atomic center structure. These metallocenes can advantageously be used in catalyst systems for the polymerization of olefins to generate a wide variety of different polymers including HDPE, LLDPE, ethylenelpropylene/(diene) elastomers, tactiospecific C3+alpha-olefin polymers, intimate mixture thereof and the like. |
