Abstract
Abstract Method of flame retarding substrates by applying Hexahydrotriazine phosphonate derivatives corresponding to the structural formula: WHERE R5 and R6 are the same or different radicals and are AND R1, R2, R3 and R4 are the same or different radicals and are alkyl, cycloalkyl, alkenyl, alkylene, aryl or aralkyl said radicals having 1 to 20 carbon atoms and are either unsubstituted or substituted by non-interfering substituents such as halogen, alkoxy, or hydroxy; and mixtures thereof and curing at a moderate temperature by free radical initiation or radiation so as to form an insoluble, fire retardant resinous finish.
