PREPOLYMER CATALYST FOR PREPAREING HIGH-DENSITY POLYOLEFIN, PREPARATION METHOD THEREOF, AND METHOD FOR PREPARING HIGH-DENSITY POLYOLEFIN USING THE PREPOLYMER CATALYST

摘要

the present invention for producing a high-density polyolefin polymer around the catalyst , a method of manufacturing the same , and that the pre- polymer catalyst used for high density relates to a method for producing polyolefins , and more particularly to magnesium-supported Ziegler -Natta catalyst , olefin and alkenyl former polymer combined total weight produced aluminum compound catalyst , and a method of manufacturing a high-density polyolefin and that I produced using a polymer catalyst as the manufacturing method, there is a separate effect of providing an efficient and economic high-density polyethylene having a high strength characteristics without the addition of a comonomer .
