ABSTRACT:
There are provided new thermoplastic compositions useful in the preparation of shaped articles, the compositions comprising, in admixture, a polyphenylene ether resin, a styrene resin and as a modifier therefor, a resinous material having a softening point above the heat distortion temperature of the total composition, the resinous material being present in an amount at least sufficient to lower the melt viscosity of the composition while molten with retention of the heat deflection temperature of the composition after molding.
