A process for preparing polynuclear metallocenes by reacting a metallocene in which one of the cyclopentadienyl-containing radicals has a substituent having olefinic or acetylenic unsaturation with a second metallocene having a metal which comes from groups IVb to VIb of the periodic table and a metal-hydride bond. The use of the resulting metallocenes in the polymerization of olefins is disclosed, including techniques for using such metallocenes to produce solid prepolymerized metallocene-containing catalyst systems suitable for use in the polymerization of olefins.
