EnglishThe present invention relates to aryloxy-substituted cyclic and polymeric phosphazenes of general formula: in which X, X', w, y and z have the meaning defined in the text, containing epoxy functions. The preparation of these products is effected by reaction between cyclo- and poly-phosphazenes having free hydroxyl functions with compounds which possess methylenic [alpha]-chloro or [alpha]-bromo groups and simultaneously contain epoxy functions, or by a reaction of epoxidation of cyclo- or poly-phosphazenes containing olefinic double bonds in the side substituent groups with organic peracids of various types.
