Polyester-based plasticizer, vinyl chloride-based resin composition containing same, and molded article thereof

Abstract

Provided are a polyester-based plasticizer which is excellent in cold resistance, non-migration, oil extraction resistance, volatility resistance and the like in a well-balanced manner, which particularly allows a molded article to be excellent in oil extraction resistance and transparency, and which can be produced from a biomass resource, and a vinyl chloride-based resin composition containing the polyester-based plasticizer and a molded article thereof. A polyester-based plasticizer obtained from a dibasic acid component (A), a glycol component (B), a hydroxy acid component (C), and an end termination component (D), wherein the component (A) is one or more selected from the group consisting of sebacic acid, azelaic acid and succinic acid, the component (B) is one or more selected from the group consisting of 1,2-propylene glycol, 1,3-propylene glycol, 1,3-butanediol and 1,4-butanediol, the component (C) is 12-hydroxystearic acid, and the end termination component (D) is one or more selected from the group consisting of a monovalent fatty acid having 8 to 12 carbon atoms and a linear monohydric alcohol having 6 to 10 carbon atoms.
