Catalyst composition and process for olefin polymerization and copolymerization using supported metallocene catalyst systems |
摘要 |
A catalyst composition includes: A) a solid catalyst precursor containing a metallocene compound, a magnesium compound and a particulate polymeric material; and B) a cocatalyst containing aluminum compound. The catalyst is prepared by combining metallocene compound, magnesium compound and particles of polymeric material to form a catalyst precursor; and activating the catalyst precursor with alkylaluminums and/or aluminoxanes. Homopolymeric or copolymeric polyolefins are produced by contacting olefins or olefins and alpha-olefins with the catalyst composition.
