Abstract
Salts of triazinic compounds with oxygenated acids of phosphorus, of the eral formula (I): ##STR1## wherein: at least one of radicals for R to R.sub.5 is: ##STR2## being: m=an integer comprised between 2 and 8; p=an integer comprised between 2 and 6; The new salts having the general formula (I) are applied, in particular, as anti-flame additives for polymers.
