Polypropylene resin composition |
摘要 |
A polypropylene resin composition comprising: 95 to 50% by weight of a propylene homopolymer (A) having an intrinsic viscosity [eta]A of not more than 1.3 dl/g; and 5 to 50% by weight of a propylene-ethylene block copolymer (B) having a propylene homopolymer portion having an intrinsic viscosity [eta]BP of from 1.4 to 2.0 dl/g, and a propylene-ethylene random copolymer portion having an intrinsic viscosity [eta]BEP of from 4.0 to 15 dl/g, the polypropylene resin composition having a melt flow rate of from 5.0 to 150 g/10 min.
