A supported titanium-containing catalyt component for .alpha-olefin polymerization is prepared by contacting a magnesium halide such as magnesium dichloride, an electron donor compound such as ethylbenzoate, an aromatic carboxylic acid or its derivative such as benzoyl chloride, an organic aluminum chloride compound such as ethylaluminum dichloride and a titanium compound such as titanium tetrachloride. The supported titanium-containing catalyst component in combination with an aluminum alkyl cocatalyst is useful for obtaining polypropylene having good bulk density.
A polypropylene-based resin composition containing 0.001 to 10.0 parts by weight of benzoic acid with or without substituent(s) on its benzene ring and/or an acid anhydride of benzoic acid, with or without substituents on its benzene rings, to 100 parts by weight of a polypropylene-based resin is disclosed. The resin can generate mouldings with improved rigidity or transparency.
