Abstract:
A thermoplastic molding composition, comprisingA) from 5 to 95% by weight of a polyester, B) from 1 to 30% by weight of a flame retardant nitrogen compound, excluding melamine cyanurate, C) from 0.1 to 30% by weight of a phosphinate of formula I or of a diphosphinate of formula II or of polymers of these or mixtures of these â€ƒwhere R1 and R2 are hydrogen, linear or branched alkyl having from 1 to 6 carbon atoms or phenyl, with the proviso that at least one of the radicals R1 and R2 is hydrogen, R3 is linear or branched C1- to C10-alkylene or is arylene, alkylarylene or arylkalkylene, M is an alkaline-earth metal or alkali metal, Al, Zn, Fe or boron, m is an integer from 1 to 3, n is an integer from 1 to 3, and x is 1 or 2, 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, and E) from 0 to 60% by weight of other additives selected from the group consisting of fillers, heat stabilizers, oxidation inhibitors, UV stabilizers, colorants, nucleating agents, lubricating and mold-release agents and fluorine containing ethylene polymers and copolymers, where the total of the percentages by weight of components A) to E) is 100%.
