Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a highly active polymer-supporting metallocene catalyst for polymerizing an olefin, to provide the produced metallocene catalyst, and to provide a method for polymerizing an alkylene in the presence of the catalyst. SOLUTION: This method for producing the highly active polymer-supporting metallocene catalyst for polymerizing the olefin comprises a process for dissolving divinylbenzene monomer, vinylbenzyl chloride monomer and an initiator in an organic solvent, mixing the obtained solution with an aqueous solution-like suspension stabilizer, and then subjecting the mixture to a suspension polymerization a 40 to 80 deg.C to obtain polystyrene; a process for swelling the obtained polystyrene in an organic solvent containing a dialcoholamine at the ordinary temperature for one to three days to obtain the dialcoholamine function-added polymer; and a process for reacting the polymer with an organic solvent containing a metallocene compound (CpM*Cl3 ).  Since used for an ethylene and a styrene polymerization reactions instead of a conventional homogeneous catalyst, the polymer-supporting metallocene catalyst can widely be used for copolymerization reactions using metallocene catalysts.
