Summary:The invention further relates to the use of the novel molding compositions for producing fibers, films or moldings, and also to the resultant moldings of any type. Thermoplastic molding compositions compriseA) from 5 to 96% by weight of a polyester,B) from 1 to 30% by weight of a phosphinate of formula I and/or of a diphosphinate of formula II and/or polymers of these  where:Rand Rare linear or branched C-C-alkyl, phenyl or hydrogen,Ris linear or branched C-C-alkylene, arylene, alkylarylene or arylalkylene,M is an alkaline-earth or alkali metal, Zn, Al, Fe or B,m is an integer from 1 to 3,n is an integer from 1 to 3,is 1 or 2 andC) from 1 to 30% by weight of at least one organic phosphorus-containing flame retardant,D) from 0 to 5% by weight of at least one ester or amide of saturated or unsaturated aliphatic carboxylic acids having from 10 to 40 carbon atoms with saturated aliphatic alcohols or amines having from 2 to 40 carbon atoms, andE) from 0 to 60% by weight of other additives, where the total of the percentages by weight of components A) to E) is 100%.
