Abstract

The present invention provides a propylene polymer molded article being high in tensile elongation and scratch resistance and a propylene polymer composition capable of affording such a molded article. Specifically, the present invention provides, in one embodiment thereof, a propylene polymer composition comprising a propylene polymer (A-1) that is a polymer having an intrinsic viscosity, as measured in tetralin at 135° C., of from 1.2 dl/g, inclusive, to 1.7 dl/g, exclusive, or a propylene polymer (A-2) that is a polymer having an intrinsic viscosity, as measured in tetralin at 135° C., of from 1.7 dl/g, inclusive, to 2.9 dl/g, inclusive, a propylene polymer (B) that is a polymer having an intrinsic viscosity, as measured in tetralin at 135° C., of from 0.5 dl/g, inclusive, to 1.1 dl/g, exclusive, and a nucleating agent.
