Process for the production of non-inflammable polytriazines

Abstract From the Canadian patent

of Disclosure, Non-inflammable high molecular weight polytriazines are obtained by condensing less than 3 mols of polyfunctional (amino)phenols with 1 mol phosphorus (oxy) trihalide in the presence of a base, subsequently reacting the still free primary amino or phenolic hydroxyl groups with cyanogen halide in the presence of a base to form cyanamide or organic ester groups and polymerizing thereafter the reaction product at a temperature of up to 350°C optionally in the, presence of polymerization promoters. The polytriazine may be used as plastics and lacquers.
