Claim:
A flame-retardant polymeric composition comprising: (i) a polymer; (ii) a triazine or a mixture of triazines of the general formula (I); where: R 1 and R 2 , which are either the same as one another or different from one another, may be: H; a C 1-6 alkyl group, either linear or branched, simple or substituted with chlorine or bromine; an aryl group, either simple or substituted with chlorine or bromine; X is chlorine or bromine; n=0, 1, 2, 3 (iii) a bismuth compound of formula Bi z A w ; where: A is X, O, CO 3 , O 2 CO 3 or any other residue capable of forming a bismuth compound; X is a halogen as defined above; z and w are integers fulfilling the valences of Bi and A; (iv) a compound selected from the group consisting of red phosphorus or a phosphorous compound alone or in combination with an organic compound capable of forming free radicals, in which: if R 1 and R 2 is H or a non-halogenated alkyl or aryl group and n=0, then A is X; the maximum content of said halogen X on the total of the components from (i) to (iv) in said composition is 1 wt %.
