摘要
A single-stage synthesis of phosphazene-containing epoxy oligomers via the direct interaction of hexachlorocyclotriphosphazene, diphenylolpropane and epichlorohydrin has been proposed. The resulting products are composed of a common epoxy-diane oligomer and an epoxyphosphazene component, with the content of the latter being up to 45 wt %. Oligomers with epoxy numbers up to 22 were characterized with the use of gel permeation chromatography, chromatography-mass spectrometry, laser mass spectrometry, 31P NMR spectroscopy, and 1H NMR spectroscopy.
