Abstract

PURPOSE: To prepare a polyethylene having a broad molecular weight distribution and improved moldability, by using a highly active polymerization catalyst obtained from a compound prepared by contacting a magnesium halide and an aluminum halide with an alcohol, etc.
CONSTITUTION: A desired polymer is prepared by polymerizing ethylene in the presence of a Ziegler-type catalyst obtained by reacting (A) a solid compound co- deposited by contacting an anhydrous magnesium dihalide (e.g. anhydrous magnesium chloride, etc.) and an aluminum halide (e.g. aluminum chloride, etc.) with an alcohol, with (B) a halogen-containing alkylaluminum (e.g. diethylaluminum chloride, etc.), and then adding (C) a titanium halide (e.g. titanium tetrachloride, etc.) to the above reaction product.
