Abstract

PURPOSE:To obtain a polypropylene polymer composition having excellent impact resistance, especially a low-temperature impact resistance without lowering rigidity, by adding an ethylene-alpha-olefin(-polyene) random copolymer and a specific thermoplastic polymer to a base polymer. CONSTITUTION:The objective polymer composition is composed of (A) 50-90pts. wt. of a polypropylene polymer having an MFR of preferably 0.1-50g/10min, (B) 5-40pts.wt. of an ethylene-alpha-olefin random copolymer and/or ethylene-alpha- olefin-polyene random copolymer preferably having an alpha-olefin content of 15-80wt.% and a Mooney viscosity of 10-350 (the iodine value of the polyene is 1-30) and (C) 3-30pts.wt. of a thermoplastic polymer produced by polymerizing a monomer containing aromatic vinyl monomer in the presence of an ethylene-alpha-olefin copolymer and/or ethylene-alpha-olefin-polyene copolymer.
