ABSTRACT:
There are provided thermoplastic compositions comprising a polyphenylene ether and a rubber modified polystyrene resin having a discontinuous phase of polystyrene particles englobed in diene rubber membranes, the particles being between about 0.1 and 0.7 microns in diameter. Such compositions provide molded articles with substantial and unexpected improvements in impact resistance and ability to transmit light in comparison with known compositions of such rubber modified polystyrenes alone or those of other polystyrenes combined with polyphenylene ethers.
