| titleOfInvention | Polypropylene composition and molded article |
| abstract | Provided is a polypropylene composition having an excellent balance between transparency, low temperature impact resistance, and stiffness. A polypropylene composition comprising: as component (1), a propylene/ethylene copolymer containing more than 1.5% by weight and not more than 4% by weight of an ethylene-derived unit; as component (2), an ethylene/propylene copolymer containing 65 to 87% by weight of an ethylene-derived unit; and 0.01 to 0.5 parts by weight of a crystal nucleating agent, based on a total of 100 parts by weight of component (1) and component (2); wherein the polypropylene composition satisfies the following requirements: 1) the weight ratio of component (1) to component (2) is in the range of 80:20 to 90:10, 2) the intrinsic viscosity of xylene solubles (XSIV) of the composition is in the range of 0.8 to 1.4 dl/g, 3) the MFR (at 230°C under a load of 2.16 kg) of the composition is in the range of 5 to 15 g/10 min., 4) the viscosity ratio defined below is in the range of 0.40 to 0.80: |
