There are provided thermoplastic polyphenylene ether resin compositions which comprise, in admixture, a major proportion of the polyphenylene ether resin, a minor proportion of a plasticizer at least sufficient to provide a plasticized composition after molding and poly(1,4-butylene terephthalate) or branched copolyester in an amount sufficient to reduce the melt viscosity of the composition without substantially reducing the heat distortion temperature and ductility properties thereof. In such compositions, there may also be present an A-B-A1 copolymeric resin as an impact modifier. In preferred instances, where said poly(1,4-butylene terephthalate) is utilized in an amount in excess of about 5% by weight, the compositions will also contain a hydrogenated A-B-A1 block copolymer. |
