摘要 |
A rubber-modified styrenic resin composition comprising (A) 100 wt. parts of a rubber-modified styrenic resin which contains 10 to 35 wt. % of soft component particles having an average particle size of 0.1 to 0.5 mum, where said soft component particles have a single occlusion structure comprising a core part which consists of a single continuous phase of a styrenic resin and a shell part which comprises a rubber polymer and occludes said core part, and (B) 0.1 to 10 wt. parts of a polymer having a solubility parameter (SP) of 8.45 to 8.70 and having no aromatic vinyl compound unit therein. This composition has excellent plane impact strength and gloss properties, as well as moldability and other physical properties, and satisfies properties required for exterior materials, wrapping materials and molded foam articles.
