PURPOSE:To provide a polypropylene composition capable of attaining high modulas and high impact strength in combination with a filler, comprising polypropylene, a rubber-like random copolymer of ethylene and propylene, and a specific modified polyethylene. CONSTITUTION:A composition comprises ; either 3 components of (A) polypropylene, (B) a rubber-like random copolymer of ethlene with propylene, and (C) a modified polyethylene, 4.3dl/g > intrinsic viscosity >=0.5dl/g, said component (C) having as a nodified group an amino, sec. amino, tert. animo, hydroxyl, tri(hydrocarbyloxy) silyl, or oxiranyl group; or 4 components of (D) polyethylene, intrinsic viscosity >=1.5dl/g, in addition to (A), (B), and (C), said composition containing at least 50wt% component (A) polypropylene. |
