METHOD FOR OBTAINING OLIHALOGENPHOSPHAZENES AND POLYHALOGENPHOSPHAZENES WITH REGULATED MOLECULAR MASS BY INTERACTION OF HALOGENOSPHORANES WITH HEXALCILDYSILAZANES Russian patent published in 2018 - IPC C08G79/02 C01B21/97

Abstract RU 2645682 C1

FIELD: chemistry.

SUBSTANCE: invention relates to the method for obtaining oligogalogenphosphazenes and polyhalogenphosphazenes. A method for obtainingh oligo- and polyhalogenphosphazenes of the general formula [X(PX₂=N)_n-PX₃]⁺A is proposed, where n=1÷5000, , or X^-, X = Cl, Br. The method allows to receive targeted connections in one stage of the interaction of crystalline halogenosphorane of the general formula RX₅ (more often RCl₅) and silazane, in particular, a widely available hexamethyldisilazane, in the environment of chlorohydrocarbon.

EFFECT: method for obtaining the oligo- and polyhalogenphosphazenes with controlled molecular weight in one stage, from available reagents, which do not require a complicated loading order of the components and characterized by a small amount of the solvent used.
