A polypropylene resin composition having a melt index of 0.5 to 20 g / 10 min, comprising 20 to 98 parts by weight of a propylene-based polymer (A) with an intrinsic viscosity (eta), measured in tetralin at 135 ° C., of 2.0 up to 5 dl / g and a melting point (Tm), determined from the peak temperature of the melting curve of 140 to 162 ° C. measured with a differential scanning calorimeter and 2 to 80 parts by weight of a propylene-based polymer (B) with an intrinsic viscosity (eta), measured in tetralin at 135 ° C., from 0.80 to 1.8 dl / g and a melting point (Tm), determined from the peak temperature of the melting curve of 160 to 166 ° C. measured with a differential scanning calorimeter, and a process for its preparation. |
