Abstract
Abstract Thermoplastic molding materials contain, as essential components, A) 5-92% by weight of a polyphenylene ether which can contain up to 50% by weight of a styrene polymer which differs from C), B) 5-92% by weight of a nylon, C) 3-50% by weight of a copolymer composed of C 1 ) 97-99.9% by weight of styrene and/or substituted styrenes of the general formula I ##STR1## where R is hydrogen, alkyl of 1 to 8 carbon atoms or halogen, R 1 is alkyl of 1 to 8 carbon atoms or halogen and n is 0, 1, 2 or 3, C 2 ) 0.1-3% by weight of an α,β-unsaturated dicarbonyl compound and C 3 ) 0-10% by weight of further, nonionic comonomers, and D) 0-35% by weight of a rubber impact modifier.
