Abstract
The present invention provides polymerization catalyst compositions employing novel dinuclear metallocene compounds. Methods for making these new dinuclear metallocene compounds and for using such compounds in catalyst compositions for the polymerization and copolymerization of olefins are also provided.
Claims21
A catalyst composition comprising a contact product of at least one dinuclear metallocene compound and at least one activator-support,
- wherein the at least one dinuclear metallocene compound is:
- or a combination thereof.
A catalyst composition comprising a contact product of at least one dinuclear metallocene compound and at least one compound selected from at least one aluminoxane compound, at least one organozinc compound, at least one organoboron or organoborate compound, at least one ionizing ionic compound, or any combination thereof;
- wherein the at least one dinuclear metallocene compound is:
- or a combination thereof.
