(57) [Problem] To provide a rubber-modified styrenic resin composition having significantly improved moldability (fluidity) without lowering impact resistance, rigidity and heat resistance. SOLUTION: The following components (A) to (D) are contained, and the total amount of the components (C) and (D) is 0.1 to 5.2 parts by weight based on 100 parts by weight of the component (A). A rubber-modified styrenic resin composition, characterized in that it is a part. Component (A): 100 parts by weight of a rubber-modified styrene resin, Component (B): More than 10 parts by weight of rosins and up to 30 parts by weight, Component (C): Low molecular weight maleic anhydride copolymer 0 to 5 Component (D): 0 to 5 parts by weight of an auxiliary agent selected from aliphatic hydrocarbons, higher fatty acids, higher fatty acid esters, higher fatty acid amides, higher fatty alcohols and metal soaps. |
