Hydroxyphenoxyphosphazenes and a process for producing same

A process for the production of a compound of the formula,

• N.sub.3 P.sub.3 (R.sub.1).sub.n (R.sub.2).sub.6-n
• wherein R.sub.1 is an isopropoxy radical having the formula ##STR7## or an aryloxy radical having the formula ##STR8## wherein each Z is independently selected for each isopropoxy radical from F and H, each X is independently selected for each aryloxy radical from Cl, Br, F and H, wherein n is a whole integer which is .gtoreq.1 and .ltoreq.5, and wherein R.sub.2 is ##STR9## or is a hydroxyphenoxy radical having the formula:
• ##STR10## in which Y is selected from Cl, Br, F and H, said process comprising, reacting an R.sub.1 -chlorocyclotriphosphazene having n R.sub.1 substituents and 6-n chloride constituents and an R.sub.2 salt for a time period sufficient to yield said compound, said reaction occurring in an inert organic solvent medium, at a temperature within the range of from about 20.degree. C. to about 150.degree. C., and with a molar ratio of said R.sub.1 -chlorocyclotriphosphazene to the R.sub.2 anion component of said R.sub.2 salt of 1:b, wherein b>5-n.
