PROBLEM TO BE SOLVED: To provide a polypropylene resin composition excellent in appearance such that a flow mark hardly occurs when formed into a molded article, that is, a high die swell and a small number of bumps, and a molded article made thereof. I will provide a. A propylene - ethylene block copolymer (i) or the propylene (i) - ethylene block copolymer and mixtures of propylene homopolymer selected from (ii), the intrinsic viscosity [η] A P polypropylene resin (a) 9 having an ethylene random copolymer portion - but propylene is 1.3 dl / g or less is a propylene homopolymer portion and the intrinsic viscosity [η] a EP is less 3.0 dl / g 5 to 80% by weight and intrinsic viscosity [η] B EP of 8.0 to 15 A propylene / ethylene block copolymer (B) having a dl / g propylene / ethylene random copolymer portion of 5 to 20% by weight, and a melt flow rate (MFR) of 5.0 to 150 g / 10 minutes. A polypropylene resin composition and a molded article comprising the same. |
