ABSTRACT:
A high flow polyphenylene ether resin composition comprises a blend of at least two polyphenylene ether resins, a first resin having an intrinsic viscosity of at least 0.3 dl/g, and a second resin having an intrinsic viscosity of less than 0.17 dl/g and preferably having a particle size of at least about 100 μm. Fiber reinforced and flame retarded compositions exhibit high HDT values.
