ABSTRACT:
This invention relates to R.sub.1, R.sub.2 -hydroxyphenoxycyclotriphosphazenes and to a process for their preparation. R.sub.1 is a phenoxy-, halophenoxy- or an isopropoxy- group while R.sub.2 is a hydroxyphenoxy- or a bis-phenoxy A group. The process comprises reacting R.sub.1 -chlorocyclotriphosphazene with an R.sub.2 salt. The reaction takes place in the presence of an inert organic solvent and at a temperature within the range of from about 20.degree. C. to about 150.degree. C.
