PURPOSE: A polypropylene resin composition is provided to improve impact strength and resistance to whitening, thereby effectively applying to electronics and interior parts of automobiles. CONSTITUTION: A polypropylene resin composition comprises 65-95 weight% of crystalline propylene polymer, 5-35 weight% of A-olefin based copolymers and 0.01-2.0 weight% of organic peroxide based on the propylene-based resin. The crystalline propylene polymer has a melt index of 0.1-500g/10min(ASTM D1238). The A-olefin based copolymers comprise one or greater kinds of copolymers of C2-20 A-olefin monomer. The A-olefin based copolymers have a density of 0.90-0.93 g/cm^3(25 deg. Celsius). |
