<p>PROBLEM TO BE SOLVED: To provide a propylene resin composition which has impact resistance, can obtain a molded body excellent in rigidity and is excellent in moldability, and to provide a molded body composed of the propylene resin composition.SOLUTION: There is provided a propylene resin composition which comprises: 99 to 51 wt.% of a propylene polymer having an isotactic pentad fraction of 0.97 or more, a ratio of a weight average molecular weight to a number average molecular weight of 4.0 or less, a weight ratio of a component having a weight average molecular weight of 14000 or less of less than 1.8 wt.% and a weight ratio of a component eluted at 90°C or less of 0.21 wt.% or less in the temperature rising elution fractionation with ortho-dichlorobenzene; and 1 to 49 wt.% of an ethylene polymer having a heat of fusion of 5.0 J/g or more as measured by a differential scanning calorimeter and a ratio of the shear viscosity of the ethylene polymer to the shear viscosity of the propylene polymer of 2.0 or less.</p> |
