A polypropylene-based resin composition. |
摘要 |
<p>The polypropylene-based composite resin composition of the invention, which can be molded into a shaped article having excellent surface hardness and impact strength at low temperatures and usable as a shell plate member of automobiles, comprises (a) a polypropylene resin as the matrix phase, (b) particles of rubber-reinforced styrene-based resin as the dispersed phase having a specified area-average particle diameter, of which the rubber particles having a specified area-average particle diameter forms a "salami" structure as dispersed in the styrene-based resin, and (c) a layer of a compatibility improver, such as a styrene-based thermoplastic elastomer, on the surface of the particles of the rubber-reinforced styrene-based resin in a specified thickness.</p> |
