| description | In a polypropylene resin composition including the following components (A) to (D) in prescribed amounts, limiting the amount of a polypropylene component having a molecular weight of 106.5 or more to less than 0.05 wt% can provide a propylene resin composition that includes an impact polypropylene and a high flow homopolypropylene and is particularly preferable for foam molding, and a molded article comprising the composition. (A) Impact polypropylene that includes 5 wt% or more and 20 wt% or less of a propylene-ethylene copolymer having an intrinsic viscosity [η] of 1.5 dl/g or more and 3.8 dl/g or less and having an MFR (230°C, 2.16 kg) of 30 g/10 min to 200 g/10 min, (B) high flow homopolypropylene having MFR (230°C, 2.16 kg) of 200 g/10 min to 1000 g/10 min, (C) ethylene elastomer having an MFR (190°C, 2.16 kg) of 0.5 g/10 min to 40 g/10 min, and (D) inorganic filler. |
