Abstract
This invention is directed to an organometal compound catalyst that is useful for polymerizing at least one monomer to produce a polymer. The catalyst is produced by combining a titanium, zirconium or hafnium organometal compound, preferably a metallocene, at least one organoaluminum compound, and a treated solid oxide. The treated solid oxide compound contains at least one halogen, zirconium and a solid oxide compound.
