Abstract: A resin composition for an automobile bumper comprising components (A), (B), and (C) described below:(A) 45 to 74% by weight of a crystalline ethylene-propylene block copolymer having (a) a flexural modulus of 15,000 kg/cm.sup.2 or more, (b) an ethylene content of 5 to 20% by weight, (c) an intrinsic viscosity (decalin, 135.degree. C.) of a portion soluble in p-xylene at room temperature of 3 or more, (d) a melt flow index (MI) of 21 to 70 g/10 min., and (e) a content of a portion insoluble in boiling n-heptane of 97% by weight or more;(B) 21 to 35% by weight of elastomer selected from the group consisting of components (I), (II) and (III) and having a weight ratio of (I) : [(I)+(II)+(III)] of from 0.5 to 1.0, (a) said component (1) being an amorphous ethylene-butene copolymer having a butene content of 10 to 25% by weight and a Mooney viscosity value, (ML.sub.1+4, 100.degree. C.
