Abstract
An object of the present invention is to provide a plasticizer for vinyl chloride-based resin superior in cold resistance and volatility resistance, and desirable in flexibility, fogging resistance, heat discoloration resistance, and weather resistance, and to also provide a vinyl chloride-based resin composition comprising the plasticizer.An ester obtained by reacting a specific carboxylic acid or a derivative thereof with a C9 saturated aliphatic alcohol at a specific proportion is superior in cold resistance and volatility resistance, and desirable in flexibility, fogging resistance, heat discoloration resistance, and weather resistance. Therefore, if becomes possible to obtain a vinyl chloride-based resin composition applicable to automobile parts, medical materials, or the like, as well as a molded article of the vinyl chloride-based resin composition.
