A polypropylene-base resin composition which comprises: (a) 80-60 wt. % of a crystalline ethylenepropylene block copolymer having an ethylene content of 11-30 wt. % and specific physical data; (b) 5-35 wt. % of an ethylene-propylene copolymer rubber having a propylene content of 20-50 wt. % and a specific Mooney viscosity; (c) 5-35 wt. % of an ethylene-propylene-a specific diene terpolymer having a propylene content of 20-50 wt. % and a specific Mooney viscosity; and (d) 2-5 wt. %, based on the total weight of the above resin components (a), (b) and (c), of an inorganic filler having a particle size of 3 mu m or smaller. The composition has excellent paintability and high stiffness, impact resistance and molding fluidity. |
