ABSTRACT:
Synthesis of new (lithiophenoxy)phosphazene high polymers is described whin 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(OC.sub.6 H.sub.4 X-p).sub.x (OC.sub.6 H.sub.4 Br)y].sub.n and [NP(OC.sub.6 H.sub.4 Li-p).sub.x (OPh).sub.y ].sub.n, where X is PPh.sub.2, PPh.sub.2 C.sub.4 H.sub.9.sup.+ Br.sup.-, SnPh.sub.3, AuPPh.sub.3, or COOH.
