<p>A rubber-modified styrene resin composition comprising (A) a rubber-modified styrene resin containing 10-35 wt.% of particles of a flexible component, which particles have a mean particle diameter of 0.1-0.5 νm and a single occlusion structure composed of a single continuous phase comprising exclusively a styrene resin as a core part and a shell part comprising a rubber polymer enclosing the core part therein and (B) a polymer having a solubility parameter SP of 8.45 to 8.70 and containing no aromatic vinyl compound unit therein. The composition is excellent in surface impact strength and gloss and also in moldability and other properties, and satisfies the performance required of exterior material, packaging material and molded foam.</p> |
