Novel Epoxy-Aryloxy Cyclotriphosphazenes with Reduced Functionality
Mixed hydroxy-aryloxy cyclotriphosphazenes have been synthesized via the interaction of hexachlorocyclotriphosphazene with a mixture of 4-allyl-2-methoxyphenol and diphenylolpropane (molar ratio 3.5 : 7.0). Their subsequent epoxidation with epichlorohydrin has afforded phosphazene-containing oligoepoxides with the phosphazene fraction of 50%. Optimal conditions for the synthesis of the composition-uniform phosphazene-containing oligoepoxides bearing one, two, and three epoxide groups in the phosphazene cycle have been elaborated. Such phosphazene-containing oligoepoxides can be cured with the curing agents common for the epoxy resins, to afford self-extinguishing compositions.
期刊介绍：
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
