PURPOSE:The titled composition suitable as fenders for motorcycles, etc., having improved impact resistance and rigidity and good luster, consisting of a specific propylene ethylene block copolymer and a specified polyethylene in a specific ratio. CONSTITUTION:(A) 100pts.wt. propylene ethylene block copolymer, having 3-50mol% ethylene content and 0.5-100g/10min melt flow rate, comprising A1: 97-40wt% propylene polymer having >=92 isotactic index, A2: 3-40wt% propylene ethylene copolymer having 40-90mol% ethylene content and 1-10dl/g intrinsic viscosity and A3: 0-20wt% ethylene polymer having 1-10dl/g intrinsic viscosity is blended with (B) 5-40pts.wt. polyethylene having >=0.9g/cm<3> density and 0.1-50g/10min melt flow rate to give a composition having 0.5-100g/10min flow rate. The ratio of melt flow of the component A and B is 0.04-1. |
