PURPOSE: To obtain a polypropylene resin compsn. excellent in stiffness, heat resistance, and impact strength. CONSTITUTION: This resin compsn. comprises 50-90 pts.wt. polypropylene resin and 10-40 pts.wt. ethylene-α-olefin copolymer whose total ethylene content is 55wt.% or higher, the ratio of the ethylene content of xylene soluble component at 25 deg.C to the total ethylene content of the copolymer is 0.90 or higher, and the component having a mol.wt. by GPC of 10,000 or lower accounts for 10wt.% or lower of the copolymer.
