β-萘酚取代聚磷腈的合成与表征 总被引:3,自引:0,他引:3
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 NMRof the title polymers were determined.The glass transition and viscous flow temperatures determined by TBAare-83℃ and 19℃respectively. Decomposition temperature measured by TGis 338℃.The Mn of Iestimated by VPOis 4110. 相似文献
