ABSTRACT:
A polystyrene based composition is provided having high impact strength and gloss. The gloss is particularly noted when the resin is molded into plastic articles, especially at relatively cooler temperatures, such as 80.degree. F. to 100.degree. F. The composition contains three resins. The first resin comprises polystyrene and rubber particles smaller than 1.0 micron, such as 0.2 to 0.6 microns. The second resin comprises polystyrene and rubber particles larger than 1.0 micron. The third resin preferably is a block copolymer of styrene and butadiene. Unexpectedly, the third resin improves the gloss achieved by the overall composition.
