The method of preparing N-dichlorophosphoryl-P-trichloromonophosphazene as monomer from PCl5 and(NH4)2 SO4 in 1,1,2,2-tetrachloroethane was investigated. Polydichlorophosphazene can be obtained from the polycondensation of this monomer and poly (β-naphthyloxy) phosphazen (I) was prepared from polydichlorophosphazene and sodium β-naphthyloxy.At the same time,the IR,31P NMR of the title polymers were determined.The glass transition and viscous flow temperatures determined by TBA are-83℃ and 19℃respectively. Decomposition temperature measured by TG is 338℃.The Mn of I estimated by VPO is 4110.
