Abstract
Mixtures of aliphatic, cycloaliphatic or aromatic polyfunctional N-cyanosulfon amides and aromatic polyfunctional cyanic acid ester are converted at 30.degree. to 150.degree. C into fusible prepolymers or prepolymers soluble in organic solvents (polymeric N-organo-isourea ethers). Said prepolymers are highly stable in storage and react at 150.degree. - 350.degree. 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.
