Abstract

PURPOSE: Ethylene is efficiently polymerized by using a catalyst consisting of the solid component obtained by contacting a mixture of magnesium dialkoxide and magnesium sulfate with titanium halide, and an organoalminum compound.
CONSTITUTION: The polymerization of ethylene in a solvent of hydrocarbon is effected in the presence of a catalyst consisting of (A) Ti-containing solid product from the reaction under heating between a mixture of a magnesium dialkoxide and magnesium sulfate (usually at a molar ratio of 1:0.05W5.0) and more than the equimolar amount of a titanium halide and (B) an organoaluminum compound. The amounts of the catalyst is preferably 0.001W5 millmoles/1 in component A and 0.01W10 millmoles/1 in component B. The pressure of the ethylene is normal one to 50kg/cm2 and the temperature is preferably 60W120°C. The present method of polymerization can give high-quality polyethylene with high density economically.
