ABSTRACT:
The processability and resistance to oxidative degradation of polyphenylene ether resins, alone, or in combination with a styrene resin, is improved by including a modifier comprising an alpha, beta-unsaturated carboxylic acid or derivative. In an embodiment, the formation of a composition comprising a poly(2,6-dimethyl-1,4-phenylene ether) and 2 parts per hundred of dibutyl maleate results in a 26 percent improvement in spiral flow, and a 30 percent reduction in oxygen uptake at 115.degree. C. enhancing the utility of polyphenylene ether resins as extrusion and injection molding materials.
