    摘要: A thermoplastic molding composition comprises, in each case based on the total of A to E,at least 3% by weight, but not more than 30% by weight, of a polyphenylene ether A,at least 10% by weight, but not more than 65% by weight, of an impact-modified styrene polymer B,at least 30% by weight of a (standard) styrene polymer C which is not impact-modified,from 0.05 to 5% by weight of a free-radical generator D,from 1 to 20% by weight of a phosphorus-containing flame retardant E, in particular an organophosphorus compound, such as triphenyl phosphate or triphenyl phosphine oxide.
