Document Type and Number:

Japanese Patent JPS595202

Kind Code:

B2

Abstract:

A supported titanium catalyst component for use in propylene polymerization is prepared by copulverizing a mixture of magnesium dichloride, titanium tetrachloride- ethylbenzoate 1: 1 adduct and hexachloroethane for 20 to 44 hrs., and then treating the resulting titanium-containing solid with n-heptane solution of hexachloroethane. Bulk polymerization of propylene in the presence of H₂ with the catalyst composed of the supported titanium catalyst component and the organo aluminum catalyst component composed of triisobutyl aluminum and ethylbenzoate at 68°C. for half an hour gives higher catalyst efficiency (above 200,000 g PP/g-Ti) and sufficient heptane insolubles (92 to 97%).
