PROPYLENE POLYMER COMPOSITION

摘要

A proplyene polymer composition having excellent whitening resistance, impat 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 a organic peroxides and (B) 0.02 - 2.0 parts by weight of an ester of an aliphatic saturated monocarboxylic acid and a polyhydic 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.
