Summary:The invention relates to a flame-retardant mixture comprising: Flame-retardant mixture comprising:a) a polymer compositionb) a phosphorus-containing compoundc) a triazine flame retardant, the weight ratio of a, b and c lying between 94:1:5 and 35:30:35, the triazine flame retardant comprising at least:c1) 1-95 wt. % melem,c2) 0.01-25 wt. % melam,c3) 0.01-20 wt. % melamine,c4) 0.1-95 wt. % higher condensation products of melamine and/or of melem, the wt. % being relative to the total of c1) up to and including c4) and together amounting to 100%, and the concentration of volatile components in the flame retardant being at most 5 wt. %. Also a process for the preparation of the triazine flame retardant.
