Olefin Polymerization Catalyst Systems and Methods for Making the Same |
| abstract |
Borate activated catalyst systems and methods for making the same for gas phase or slurry phase olefin polymerization are provided. The catalyst system can include a first catalyst comprising a borate activated mono cyclopentadienyl metallocene compound and a second catalyst comprising a supported bis cyclopentadienyl metallocene complex. A supported bis cyclopentadienyl metallocene complex can be prepared to provide a preformed, supported catalyst, wherein the supported bis cyclopentadienyl metallocene complex comprises bis(1,3-methylbutyl cyclopentadienyl) zirconium dichloride. The preformed, supported catalyst can be mixed with mineral oil or hydrocarbon solvent to form a slurry. The slurry can be mixed with a borate activated mono cyclopentadienyl metallocene compound to form the borate activated catalyst system. |
