Abstract : Synthesis of new(lithiophenoxy)phosphazene high polymers is described wherein polymers such as poly(dichlorophosphazene) are used as the starting material to prepare poly(organophosphazenes) by reaction thereof with sodium para-bromophenoxide. Poly(organophophazenes) thus obtained are used in a metal-halogen exchange reaction with n-butyllithium. The lithio derivatives thus obtained are used as reactive intermediates for the synthesis of polymers of formulas (NP(OC6H4X-p)x(OC6H4BR)y)n and (NP(OC6H4Li-p)x(OPh)y)n, where X is PPh2, PPh2, PPh2C4H9+Br-,SnPh3, AuPPh3, or COOH.
