Abstract
This invention relates to self-extinguishing polymeric compositions, comprising a thermoplastic polymer, preferably a polyolefin, and an anti-flame additive consisting of: PA1 (1) 10-25% by weight, on the total composition, of an ammonium or amine phosphate; and PA1 (2) 10-25% by weight, on the total composition, of a product obtained by reacting in bulk, at a temperature comprised between 80.degree. C. and 230.degree. C., PA2 (a) at least one organic compound selected from the group consisting of PA3 (i) linear or cyclic nitrogen containing compounds having at least one >C.dbd.O or >C.dbd.S group and at least one --NH--group being part of the linear chain or of the ring, and PA3 (ii) amino-triazine compounds; with PA2 (b) an epoxyalkyl ester of isocyanuric acid of the formula: ##STR1## 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 compositio…
