Low flue gas thermoplastic molding compositions containing A) 5 to 94% by weight of a polyphenylene ether, B) 5 to 94% by weight of a vinyl aromatic polymer, C) 1 to 30% by weight of a flame retardant and D) 0 to 60% by weight % of conventional additives in effective amounts, characterized in that component C) from a mixture of C1) at least one phosphine oxide of the general formula I <IMAGE> where R¹, R² and R³ have the same or different alkyl, aryl, alkylaryl or cycloalkyl groups 8 to 40 carbon atoms and C2) at least one phosphate of the general formula II <IMAGE> in which the substituents R <4>, R <5> and R <6> are the same or different alkyl, aryl, alkylaryl or Mean cycloalkyl groups with 8 to 40 carbon atoms, and C3) a boron compound is built up. |
