Abstract
Thermoplastic resin compositions which contain specified weight proportions of a polyphenylene ether resin, a polyamide resin and a rubber polymer consisting of a mixture of ABA or ABA' types of block copolymers and an AB block copolymer are improved by the presence of a miscibility enhancer. Representative of the miscibility enhancers are citric acid, malic acid, maleic anhydride, trimellitic chloride anhydride and the like. The compositions of the invention have been found to produce molded articles of improved low-temperature impact properties.
