Abstract
There are provided thermoplastic compositions comprising a polyphenylene ether and a rubber modified polystyrene resin having a discontinuous phase comprised largely of particles consisting of a core of polystyrene in a shell of a diene rubber membrane, said particles constituting at least 30 percent of the total volume of the rubber-modified polystyrene. Such compositions provide molded articles with substantial and unexpected properties in impact resistance, transparency and surface gloss, particularly at low mold temperatures, in comparison with known compositions of rubber modified polystyrene alone or those of other polystyrenes combined with polyphenylene ethers.
