PURPOSE:To obtain a propylene resin molding having excellent coatability, printability, adhesion, etc., by previously blending an org. peroxide with a propylene resin in a specified weight ratio, melt-kneading the mixture, molding it and treating the surface of the molded article with low-temperature plasma. CONSTITUTION:0.005-0.2pts.wt. org. peroxide such as di-t-butyl peroxide or t-butylcumyl peroxide is blended with 100pts.wt. propylene resin such as propylene homopolymer, propylene/alpha-olefin random copolymer or block copolymer, and the mixture is melt-kneaded and molded. The surface of the molded article is treated with low-temperature plasma to obtain the desired propylene resin molding. The low-temperature plasma treatment is carried out by exciting low- pressure oxidizable gas such as oxygen gas by high-frequency or microwave discharge to generate activated gas and contacting the surface of the article with the gas. |
