Abstract
Self-extinguishing polymeric compositions, including a thermoplastic polymer and a flameproof additive whose essential components are: PA1 (A) an ammonium phosphate or an amine phosphate; PA1 (B) one or more organic compounds capable of providing, by thermal decomposition, uninflammable gaseous products and carbonaceous residues; and PA1 (C) an ester of the isocyanuric acid of general formula: ##STR1## in which R.sub.1, R.sub.2, R.sub.3, either like or unlike one another, are linear or ramified alkylene groups having 1 to 6 chain-linked carbon atoms, and Z.sub.1, Z.sub.2, Z.sub.3 are --OH or ##STR2## the (B)/(C) ratio by weight varying from 10:1 to 1:10, and components (A) and (B)+(C) being employed each at the rate of 5 to 30% by weight on the total composition.
