Zusammenfassung:What are described are flame retardant mixtures comprising a) salt of a phosphinic acid of the formula (I) n which R1 and R2 are independently alkyl, cycloalkyl, aryl or aralkyl that are optionally substituted, M is an m-valent cation, and m is 1 to 4, b) salt of a phosphinic acid of the formula (II) that differs from component a) in which R3 is optionally substituted alkyl, cycloalkyl, cycloalkylalkyl, aryl or aralkyl, preferably with alkyl radicals as substituents, R4 is alkyl with an even number of carbon atoms, with the proviso that, if R1 and/or R2 are alkyl, R4 has twice, three times or four times the number of carbon atoms of R1 or R2, M is an n-valent cation, and n is 1 to 4, c) organylphosphonate, d) phosphite, e) silicate, alumosilicate and/or silicon dioxide which is solid at 25?C,
