POLYPROYLENE RESIN COMPOSITION, MOLDED ARTICLE THEREOF, AND AUTOMOBILE INTERIOR AND EXTERIOR MATERIALS USING THE SAME

摘要

The present invention , the impact resistance , tensile breaking elongation and is excellent in rigidity polypropylene resin composition , the molded article his and it is provided with an external material in the automotive . Specifically, in the composition , the polypropylene -based polymer (A) 50 to 90 % by weight , ethylene - - olefin copolymer rubber (B) 5 to 50 mass% and a vinyl aromatic monomer unit and a subject of an alkylene monomer units as a copolymer , the content of the - olefin is an alkylene monomer units with respect to all the monomers for the polypropylene-based resin composition containing not less than the copolymer (C) 0.1 to 5 mass % 45 mol%.
