Self-extinguishing polymeric compositions based on thermoplastic polymers, comprising, for 100 parts by weight of total composition: (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: <IMAGE> wherein: <IMAGE> or a heterocyclic radical containing in the ring at least a nitrogen atom, and linked to the triazine ring through one of such nitrogen atoms, R1=alkyl or cycloalkyl, R2=divalent radical of piperazine, of the type <IMAGE> or a divalent radical of the type <IMAGE> n=an integer from 20 to 50, extremes included, m=an integer from 2 to 6, extremes included. |
