Flameproofed thermoplastic molding materials contain (A) 40-99% by weight of a partly aromatic amide copolymer consisting essentially of (a1) 40-50% by weight of units derived from terephthalic acid and hexamethylenediamine, (a2) 0-50% by weight of units derived from epsilon -caprolactam and (a3) 0-60% by weight of units derived from adipic acid and hexamethylenediamine, components (a2) and/or (a3) accounting altogether for not less than 10% by weight of the total number of units, (B) 1-30% by weight of a flameproofing combination of (b1) 40-97% by weight of red phosphorus, (b2) 1-50% by weight of an inorganic compound of a divalent or tetravalent metal, (b3) 1-40% by weight of an organic mono- or dicarboxylic acid and (b4) 1-40% by weight of an ester of an organic carboxylic acid of 6 to 24 carbon atoms with an alcohol of 2 to 24 carbon atoms or of a metal salt of such an acid, or a mixture of these, (C) 0-60% by weight of fibrous or particulate fillers or a mixture of these, and (D) 0-40% by weight of a polymeric impact modifier. |
