Abstract
Abstract This invention relates to self-extinguishing polymeric compositions, comprising a thermoplastic polymer, preferably a polyolefin, and an anti-flame additive consisting of: (1) 10-25% by weight, on the total composition, of an ammonium or amine phosphate; and (2) 10-25% by weight, on the total composition, of a product obtained by reacting in bulk, at a temperature comprised between 80 DEG C. and 230 DEG C., (a) at least one organic compound selected from the group consisting of (i) linear or cyclic nitrogen containing compounds having at least one >C=O or >C=S group and at least one -NH-group being part of the linear chain or of the ring, and (ii) amino-triazine compounds; with (b) an epoxyalkyl ester of isocyanuric acid of the formula: <IMAGE> wherein n is an integer from 1 to 3; the reaction being carried out according to a molar ratio (a):(b) comprised between 3:1 and 0.1:1. The invention also includes paints and coatings containing the above-mentioned self-extinguishing polymeric compositions. The invention also includes articles having self-extinguishing properties by the application thereto of the above-mentioned polymeric compositions.
