Abstract
Ethylene is polymerized in the presence of a catalyst comprising: (A) the reaction product of a magnesium compound and titanium halide and (B) an organic aluminum compound wherein Component A is prepared by reacting magnesium dialkoxide with a halogen-containing silicon compound and an alcohol to provide a solid material and then reacting the solid material with titanium halide in the presence of an alkoxy-containing silicon compound.
