ABSTRACT:
A polymerization process comprising contacting at least one olefin under polymerization conditions with a catalyst composition produced by combining an organoaluminoxane cocatalyst and a polymeric metallocene catalyst prepared by (1) forming a fluorine-containing polymer by (a) polymerizing a 2-vinyl fluorenyl compound or (b) polymerizing a fluorenyl compound by reacting it with chloro methyl methyl ether in the presence of zinc dichloride or aluminum trichloride; (2) reacting the fluorenyl-containing polymer with an alkali metal compound; and (3) reacting the product of step (2) with a transition metal-containing compound.
