Abstract
Amelinic compounds of general formula (I) ##STR1## obtained by subsequent condensation reaction of 1 mol of a cyanuric acid lide with 1 mol of amine and of a polyamine and by hydrolysis reaction of the thus obtained intermediate. Compounds of general formula (I) are used, in particular, as antiflame additives.
