Abstract
A propylene polymer composition having excellent whitening resistance, impact resistance, rigidity and flowability. The propylene polymer composition comprises (A) 100 parts by weight of a propylene polymer or a modified polymer obtained by heat-treating the propylene polymer in an organic peroxides and (B) 0.1 to 1.5 parts by weight of an ester of an aliphatic saturated monocarboxylic acid and a polyhydric alcohol, and the propylene polymer essentially consists of two particular polymer fractions or three particular polymer fractions polymerized over stereoregular catalysts and combinationed in a specific ratio.
