Abstract: An improved polyphenylene ether composition is described herein, comprising at least two polyphenylene ether resins, one having an intrinsic viscosity of at least about 0.38 dl/g, and another having an intrinsic viscosity of no greater than about 0.33 dl/g. The use of a blend of two PPE resins has unexpectedly resulted in a level of increased melt flow which was much greater than one would predict from the calculated melt flow for a PPE resin having an intrinsic viscosity (IV) which was the average of that of two such PPE resins.
