Abstract

PURPOSE: Title composition in which barium sulfate and an amorphous ethylene- propylene copolymer with a specific intrinsic viscosity are admixed to a crystalline polypropylene, thereby giving molded products with high stiffness, impact strength and good surface luster.
CONSTITUTION: (A) a crystalline polypropylene is mixed with (B) 10W40, preferably 15W30 wt%, based on the resulting composition, of barium sulfate with an average particle size of less than 2 microns and (C) 2W20, preferably 3W15 wt% of an amorphous ethylene-propylene copolymer with an intrinsic viscosity of less than 1.9 measured in xylene at 70°C and they are kneaded with a roll mill or the like. When necessary, an antioxidant, ultraviolet absorber, lubricant and others are added.
