Physically blended propylene polymer composition

A physically blended propylene polymer composition comprising

• (A) 100 parts by weight of crystalline polypropylene containing 0 to 10 mole% of a member selected from the group consisting of ethylene, another .alpha.-olefin, and a mixture thereof,
• (B) 1 to 30 parts by weight of a propylene/ethylene random copolymer composed of 30 to 85 mole% of propylene, said copolymer containing 0 to 10 mole% of a diene component and having (i) a micro-isotacticity of at least 0.8 and (ii) a boiling n-cyclohexane insolubles content of 0 to 10% by weight, said random copolymer being prepared by using a catalyst comprising a carrier-supported solid titanium catalyst component containing magnesium, halogen, titanium and an electron donor, and an organoaluminum compound catalyst component, and
• (C) 0 to 30 parts by weight of polyethylene containing 0 to 15 mole% of an .alpha.-olefin, said components (A) and (B) having been physically mixed with each other.
