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

摘要

There are provided a polypropylene-based resin composition having excellent impact resistance, tensile elongation at break and rigidity, a molded article thereof, and an automobile interior or exterior material using the same. The polypropylene-based resin composition contains 50 to 90% by mass of a polypropylene-based polymer (A), 5 to 50% by mass of an ethylene-α-olefin copolymer rubber (B), and 0.1 to 5% by mass of a copolymer (C) primarily comprising a vinyl aromatic monomer unit and an alkylene monomer unit, wherein a content of an α-olefin monomer unit in all alkylene monomers is 45 mol % or more.
