A CATALYST FOR PREPARATION OF ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE AND A PREPARATION METHOD OF ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE USING THE SAME

摘要

PURPOSE: A catalyst for manufacturing high molecular weight polyethylene is provided to have excellent catalyst activity through a simple manufacturing process and to manufacture a solid complex titanium catalyst with a controlled particle shape. CONSTITUTION: A catalyst for manufacturing high molecular weight polyethylene is manufactured by a step of preparing a support by conduct a reaction of magnesium alkoxide compound and organic aluminum compound; and a step of conduct a reaction of the support and titanium compound. A manufacturing method of a ultrahigh molecular weight polyethylene comprises a step of polymerizing ethylene under the presence of the solid complex titanium catalyst and organic metal compound. The organic metal compound is an organic aluminum compound.
