    Abstract: Vinylbenzyl derivatives are obtained by reaction of vinylbenzyl halides with alkali metal cyanates, in the presence of a polymerisation inhibitor, in a polar solvent containing a nitrogen atom or a sulphur atom but free of active hydrogen atoms in the molecule, in the presence or in the absence of a compound containing an active hydrogen, and at a temperature between 25 and 200 DEG C. Tris(vinylbenzyl) isocyanurate is obtained by such a reaction, in the absence of a compound containing an active hydrogen, whereas di(vinylbenzyl)urea is obtained by the reaction in the presence of water, and an N'-substituted vinylbenzylurea is obtained by the reaction in the presence of an amine.

    Abstract: Isocyanuric acid triesters are prepared by isomerization of the corresponding cyanuric acid triesters. The starting cyanuric acid esters are dissolved in a polar solvent which is free of active hydrogen atoms, which contains a nitrogen or sulfur atom in the molecule and which has a boiling point not higher than 260 DEG C. The solution may optionally contain an alkali metal halide, an alkaline earth metal halide or an ammonium halide. Isomerization is carried out at a temperature of from 50 DEG to 200 DEG C.
