Zusammenfassung:	The flame resistance of blends of polyphenylene ether resin and high impact polystyrene is upgraded by including both a brominated polystyrene and antimony oxide, which work in synergistic combination in the compositions. The present flame retardant combination not only exhibits good heat stability, but unlike many prior art flame retardants of greater volatility, also resists migration to the surface. Le pouvoir ignifuge de mélanges de résine d'éther de polyphénylène et de polystyrène à impact élevé est amélioré en incorporant audit mélange à la fois un polystyrène bromé et de l'oxyde d'antimoine, lesquels agissent en combinaison cynergique dans les compositions. Ladite combinaison ignifuge non seulement présente une bonne stabilité thermique mais, à la différence de nombreuses préparations ignifuges antérieures de volatilité supérieure, résiste également à la migration en surface.
