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

摘要

Provided are a polypropylene resin composition having excellent impact resistance, tensile elongation at break, and rigidity, as well as a molded article thereof and automobile interior and exterior materials using the same. The polypropylene resin composition comprises 50 to 90 mass% of a polypropylene polymer (A), 5 to 50 mass% of an ethylene-α-olefin copolymer rubber (B), and 0.1 to 5 mass% of a copolymer (C), the primary components of which are vinyl aromatic monomer units and alkylene monomer units and wherein the α-olefin monomer unit content of the total alkylene monomer units is 45 mol% or greater.
