A polyphenylene ether composition comprises polyphenylene ether, optionally styrene resin, and a diamide represented by the formula
wherein R' is a C1-10 linear or branched saturated or unsaturated aliphatic hydrocarbon residue, an alicyclic hydrocarbon residue, an aromatic hydrocarbon residue, or such a residue having one or more substituents; and R2 and R3, which may be the same of different, are each a C1-10 linear or branched saturated or unsaturated aliphatic hydrocarbon residue, an alicyclic hydrocarbon residue or an aromatic hydrocarbon residue, or such a residue having one or more substituents.
The composition has improved processability, due to high flowability, with a minimum decrease in heat resistance.
