Styrene-based resin composition, injection molded article, vehicle component, and dissimilar resin composite member

Abstract

The problem solved by this disclosure is to provide a styrene-based resin composition excellent in heat resistance, toughness, rigidity, and weldability with acrylic resin materials. This disclosure is a styrene-based resin composition including a styrene-unsaturated carboxylic acid-based resin (A) containing styrene-based monomer units (a1) and unsaturated carboxylic acid-based monomer units (a2), and core-shell structured rubbery particles (B) containing (meth)acrylic acid ester monomer units (b1), wherein the content of the styrene-unsaturated carboxylic acid-based resin (A) is 40 mass % to 95 mass %, and the content of the rubbery particles (B) is 5 mass % to 60 mass %, relative to the total amount (100 mass %) of the styrene-based resin composition.

Dependencies are inferred from the claim text.
