FIELD: chemistry.
SUBSTANCE: method includes interaction of diatomic phenol, epichlorohydrin and chlorocyclophosphazene. As chlorocyclophosphazene used is hexachlorocyclotriphosphazene or its mixture with higher chlorocyclophosphazenes[NPCl2]n, where n=4-15. Synthesis is carried out by direct interaction of said reagents in presence of bases. Diphenol is taken in quantity from 2 to 120 moles per NPCl2 unit, and epichlorohydrin is taken in not less than 2-fold excess with respect to diphenol.
EFFECT: elaboration of simple and technological method of synthesis of epoxyphosphazenes, characterised by high content of epoxy groups and easily compatible with industrial epoxy resins of ED type with application of available resources.
