Abstract of the Disclosure Polyfunctional aminophenols or amino(alkyl)phenols are converted with cyano halide in the presence of a base at temperatures below 65°C into the corresponding aro- matic cyanic acid esters containing cyanamide groups and thereafter at 65°C to 150°C into prepolymers which are soluble in organic solvents and highly stable in storage. The prepolymers may be converted into high molecular weight polymers of triazine structure by heat- ing to 150°C to 350°C. The end products are insoluble in solvents and are infusible. The prepolymers ma be used for the production coatings, shaped articles or laminates.
