A polymer bound ligand represented by the formula QM(R)m and process for preparing same are provided, wherein Q is a polystyrene, M is Si, C, Ge, Sn, P, or N, each R is a that at least one R is a cyclopentadienyl-type compound, and m is 2 or 3, said process comprising reacting a metallated polystyrene and an organohalide compound, wherein the polystyrene is metallated with an alkali metal, and wherein said organohalide compound is represented by the formula XM(R)m wherein X is a halide. Other aspects of the present invention include a polymer bound metallocene represented by the formula QM(R)mZYn and a process for preparing same, wherein Z is a transition metal, Y is a halide, methyl, hydrogen, or a cyclopentadienyl-type group, and n is 2 or 3 . Other aspects of the present invention include a catalyst system comprising the polymer bound metallocene and an organoaluminoxane, a method for preparing same, and a polymerization process employing the catalyst system.
