Abstract

Phosphazene-containing epoxy oligomers (PEOs) were synthesized by the one-pot method by means of the interaction of hexachlorocyclotriphosphazene, diphenylolpropane, and epichlorohydrin at 80°C in the presence of solid KOH. In contrast to similar PEOs previously obtained at a lower temperature, according to MALDI–TOF spectrometry, the phosphazenes synthesized in this work contain about 10% of compounds with two or three phosphazene rings linked by one or two oxyaryleneoxy radicals, while the total number of epoxide groups in the molecules of these compounds is from four to eight. PEOs are cured with polyamine hardeners to form compositions with increased fire resistance, while retaining the basic properties of conventional epoxy materials.
