The subject of the invention is compounds corresponding to the formula <IMAGE> in which R represents an allyl radical, Y represents a chlorine atom or an R radical, X represents a monovalent residue such as -P(O)Cl2, x is equal to 1 or 2 and n is an integer from 1 to 10,000. These compounds are obtained by photochemical substitution of the chlorine atoms of a polydichlorophosphazene or of P-trichloro-N-(dichlorophosphoryl)monophosphazene by an organotin derivative.
