Abstract

PURPOSE: To prepare a polyethylene having a broad molecular weight distribution and excellent moldability, by using a Ziegler-type catalyst obtained from a compound prepared by contacting magnesium hydroxide with an aluminum alkoxide, etc.
CONSTITUTION: A desired polymer is prepared by polymerizing ethylene in the presence of a catalyst obtained by reacting (A) a magnesium compound prepared by contacting magnesium hydroxide with an alminum alkoxide (e.g. aluminum isopropoxide, etc.), with (B) a titanium halide (e.g. titanium tetrachloride, etc.), and then adding (C) an organoaluminum compound (e.g. triethylaluminum, etc.) to the above reaction product.
