METHOD FOR PREPARING ZIEGLER-NATTA CATALYST FOR POLYMERIZATION OF HIGH DENSITY POLYETHYLENE, ZIEGLER-NATTA CATALYST, AND POLYETHYLENE

摘要

The present invention relates to a method for preparing a Ziegler-Natta catalyst for high-density polyethylene polymerization, a Ziegler-Natta catalyst prepared thereby, a method for producing polyethylene using the catalyst, and a polyethylene produced thereby, by reacting a magnesium compound with an alcohol to form a magnesium compound Preparing a solution, adding water to the magnesium compound solution and reacting to prepare a hydrogenated magnesium compound solution, and reacting the hydrogenated magnesium compound solution with an aliphatic hydrocarbon or aromatic hydrocarbon solvent containing a transition metal compound to form solid particles It includes the steps of manufacturing.
