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 [&eegr;] measured in tetralin at 135Â° C. of 2 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 162Â° C.; and 2 to 80 parts by weight of a propylene-based polymer B having an intrinsic viscosity [&eegr;] measured in tetralin at 135Â° C. of 0.8 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 166Â° C., wherein the total amount of the propylene-based polymers (A) and (B) is 100 parts by weight.
