PURPOSE:To provide the title molding which has no fear of harmful metal elements being dissolved out, has excellent toughness and chemical resistance and is inexpensive, by blending a beta-aminocrotonate with a chlorine-contg. resin to stabilize it and molding it into the desired shape. CONSTITUTION:1.0-3.0 pts. wt. beta-aminocrotonate of the formula (wherein R is a residue of a mono- to Rexahydric alcohol; n is 1-6) is blended with 100 pts. wt. chlorine-contg. resin such as PVC resin or ethylenized vinyl chloride resin to obtain a stabilized chlorine-contg. resin. The resin is molded into the desired shape such as packaging container for semiconductor parts, cases for apparatuses, etc.
