To produce a polypropylene resin composition excellent in elastic modulus in bending and heat resistance.
This resin composition consists of (A) 40-99 pts.wt. of polypropylene resin, (B) 1-60 pts.wt. of talc and (C) 0.001-5 pts.wt. of a crystallization promoter per 100 pts.wt. of (A)+(B) is produced. On this occasion (A) the polypropylene resin is a highly stereo regular polypropylene resin satisfying Tp≥119.49-0.2591(log MFR) where the melt flow rate(MFR) of the polypropylene resin is observed according to ASTM D1238 and the (Tp) is the elution peal temperature of the resin observed at 0-200°C by programmed fractionation allowing to elute by holding 5-100min at each temperature rising at the intervals of 0.5-10°C after adsorption on the column. The polypropylene resin(A) and crystallization promoter (C) are melt-blended and further melt-blended with talc (B).
