<P>PROBLEM TO BE SOLVED: To provide a propylene resin composition excellent in mechanical properties such as elongation, impact resistance and low-temperature impact resistance and flowability. <P>SOLUTION: There is provided the propylene resin composition containing ≥55 pts.mass and ≤98 pts.mass of a propylene polymer (A) satisfying the following requirements [1] to [5] and ≥2 pts.mass and ≤45 pts.mass of an elastomer (B). [1] MFR is ≥100 g/10 min and ≤1,000 g/10 min, [2] the melting point is ≥150°C and ≤165°C, [3] the sum of the position irregular unit based on 2,1-bonds and the position irregular unit based on 1,3-bonds of propylene monomers in total propylene constituent units is ≥0.0% and ≤1.0%, [4] the content of components having a molecular weight of ≤10,000 is ≤7 mass%, and [5] the half-value width of the peak of elution quantity to elution temperature is ≤6.0°C and the peak top temperature is ≥100°C and ≤130°C determined by CFC using o-dichlorobenzene. <P>COPYRIGHT: (C)2013,JPO&INPIT |
