Abstract

Impact-improved polyphenylene ether resin compositions which also exhibit improved melt behavior without degradation of other themal properties are provided by combining a polyphenylene ether polymer, an alkyl or aralkyl sulfonate of an alkali metal, where the alkyl or aralkyl radical has 5 to 25 carbon atoms, and an acrylate-styrene-acrylonitrile terpolymer.
