METALLOCENE CATALYST SYSTEM FOR MANUFACTURING ETHYLENE POLYMER AND METHOD FOR MANUFACTURING ETHYLENE POLYMER BY USING SAME

摘要

The present invention provides: a catalyst system comprising a cocatalyst comprising an aluminoxane compound and/or an aluminum compound and/or boron together, with two metallocene catalysts having a specific structure; and a polyethylene polymer having a properly controlled molecular weight distribution by a method for manufacturing a copolymer of ethylene and alpha-olefin in the presence of the catalyst system, particularly provides a method for manufacturing a product having excellent physical properties for a polyethylene of raised temperature resistance (PERT) product.;COPYRIGHT KIPO 2019
