PURPOSE: To provide a vinyl chloride-based resin composition capable of producing a product in which elusion of metal ions or organic materials from the vinyl chloride-based resin composition is very low and, therefore, preferably useful for a production machine for an electronic component such as a semiconductor, a packaging vessel, its machine casing and uses related to biochemistry, medical treatment and food.

CONSTITUTION: This vinyl chloride-based resin composition is prepared by adding 0.5 to 5phr acrylic copolymer having a ratio of copolymerization of 40 to 60wt.% methyl methacrylate and 60 to 40wt.% butyl methacrylate and ≤400000 molecular weight to 100phr vinyl chloride-based resin and admixing only a tin-based metallic compound such as an organotin maleate-based substance or a sulfur-containing organotin maleate as a stabilizer.
