Abstract of Disclsosure Mixtures of aliphatic, cycloaliphatic or aromatic poly- functional N-cyanosulron amides and aromatic polyfunctional cyanic acid ester are converted at 30 to 150°C into fusib- le prepolymers or prepolymers soluble in organic solvents polymeric N-organo-isourea ethers). Said prepolymersare highle stable in storage and react at 150 - 350°c to high molecular weight polymers of of triazine structure which are insoluble in solvents and infusible. The prepolymers may be used for the production of coatings or shaped articles or laminates.
