Polypropylene resin composition and process for producing the same

Abstract

A polypropylene resin composition having a melt flow rate of 0.5 to 20 g/10 min., comprising 20 to 98 parts by weight of a propylene-based polymer (A) having an intrinsic viscosity [η] measured in tetralin at 135° C. of 2.0 to 5 dl/g and a melting point Tm determined from the peak temperature of the melting curve measured by a differential scanning calorie meter of 140 to 162° C. and 2 to 80 parts by weight of a propylene-based polymer B having an intrinsic viscosity [η] measured in tetralin at 135° C. of 0.80 to 1.8 dl/g and a melting point Tm determined from the peak temperature of the melting curve measured by a differential scanning calorie meter of 160 to 166° C. and a process for producing the same.
