    Abstract: The invention relates to thermoplastic compositions comprising an aromatic polyether containing thio, sulphone, alkylene and/or carbonyl groups polymerised into the main chain, optionally at least one other polymer from the group consisting of polycarbonates, polyterephthalates and ABS, optionally conventional additives in conventional amounts, and additionally from 0.05 to 2% by weight of a stabiliser of the formula (I). in which R , R and R are identical or different and may be C4- to C20-alkyl, C5- to C8-cyloalkyl, optionally substituted C6- to C20-aryl or O-, S- or N- containing 5- to 6-membered heterocyclic radicals, and to the use of the mixtures for conversion into mouldings. In particular, the C6- to C20-aryl radicals are substituted by OH and/or C1- to C9-alkyl radicals, and the radicals R , R and R are C4- to C12-alkyl, C5- to C6-cycloakyl and/or C6- to C20-aryl groups.
