The polyphenylene ether resin provides a mixture of polyphenylene ether resin and crystalline resin having an intrinsic viscosity of less than about 0.30 dl / g. The mixture has an increased heat deflection temperature as compared to a composition containing a polyphenylene ether resin having a higher intrinsic viscosity. The mixture may further contain admixtures, impact modifiers and reinforcing fillers.
