PURPOSE:To obtain a molded article free from Pb, Sn, etc., suitable for semiconductor production equipment etc., by molding a chlorine-contg. resin incorporated with an aminocarboxylic acid, epoxy compound, and e.g., polyhydric alcohol having neopenta type skeleton. CONSTITUTION:The objective article can be obtained by blending (A) 100pts.wt. of a chlorine-contg. resin with an average polymerization degree 600-800 consisting mainly of vinyl chloride, (B) each 0.5-5(pref. 1-3)pts.wt. of an aminocarboxylic acid (pref. beta-aminocrotonic ester) and epoxy compound (pref. glycidyl ether or glycidyl ester), and (C) 1-6pts.wt. (up to 3pts.wt. in case of press molding) of either polyhydric alcohol having neopenta type skeleton (e.g., monopentaerythritol), its ester or trimellitic ester (pref. tristearyl trimellitate) followed by molding into a desired shape.
