PURPOSE:To improve the primary adhesivity and the secondary adhesivity in the painting and bonding, etc., of the surface of a molded polyolefin resin, remarkably, by molding a polyolefin resin compounded with a specific amount of nucleation agent, and treating the surface of the molded article with plasma. CONSTITUTION:The surface of a molded article of a composition obtained by compounding (A) 100pts.wt. of a polyolefin resin (preferably a polymer composed mainly of propylene) with (B) 0.01-2pts. of a nucleation agent (e.g. dibenzylidene sorbitol), is treated with plasma, usually under 0.1-3.0 Torr pressure for preferably 3sec-20min. |
