STYRENIC RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a styrenic resin composition having excellent transparency, physical properties and especially chemical resistance. SOLUTION: The styrenic resin composition for forming a transparent molded article is composed of (A) a styrene-(meth)acrylate copolymer and (B) a crystalline ester polymer. The weight ratio of A and B satisfies the formula 0.1≤B/(A+B)<0.6. The styrene-(meth)acrylate copolymer of the component A is a copolymer composed of a styrenic constituent unit and a (meth)acrylic acid ester constituent unit and the crystalline ester polymer of the component B is a crystalline hetero-chain polymer compound having a carboxylic acid ester group in the repeating unit of the main chain.
