Self-extinguishing polymeric compositions based on thermoplastic polymers, comprising, for 100 parts by weight of total composition:n 1) from 10 to 20 parts by weight of an ammonium phosphate or of an amine phosphate; and 2) from 5 to 8 parts by weight of an oligomer or polymer derived from 1,3,5-triazine, having general formula:n wherein:n X = R 1 -NH group, or a heterocyclic radical containing in the ring at least a nitrogen atom, and linked to the trizine ring through one of such nitrogen atoms, R, = alkyl or cycloalkyl, R 2 = divalent radical of piperazine, of the typen or a divalent radical of the type n = an integer from 2 to 50, extremes included, m = an integer from 2 to 6, extremes included. |
