ABSTRACT:
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.degree. C, optionally in the presence of polymerization promoters. The polytriazine may be used as plastics and lacquers.
