摘要： Disclosed herein is a preparation process for polypropylene-base resin compositions, which process comprises heating at a temperature of 170.degree.-280.degree. C. a mixture containing a crystalline ethylenepropylene block copolymer having a specific composition, an ethylene-propylene copolymer rubber having a specific composition and viscosity, an inorganic filler having a specific particle size, and an organic peroxide, all in specified amounts. The thus-obtained polypropylene-base resin compositions are suitable for use in the production of large moldings such as automobile bumpers, fenders and body sidemembers because of their excellent low-temperature impact resistance, high molding fluidity, good paintability and high stiffness as well as their low preparation cost.

摘要： The surface of a product molded of polyolefin is washed with a fluorine-containing organic solvent such as CCl.sub.2 F--CCl.sub.2 F or CCl.sub.2 F--CClF.sub.2 and, thereafter, the product surface is treated with a plasma. Since the product surface is washed with an organic solvent containing fluorine, wastewater and process operation can be controlled with relative ease. A painted product pretreated by the process of the invention has a high peel strength and water resistance.
