SYNTHESIS AND CHARACTERIZATION OF INORGANIC POLYMER OF POLY(BIS PHENOXYL) PHOSPHAZENE

Inorganic polymer of poly(bisphenoxy) phosphazene was prepared from nucleophilic substitute reaction of reactive inorganic polymer of poly(dichlorophosphazene), which was synthesized by thermal initiated ring-open polymerization. Its structure and property was characterized by NMR, IR, GPC, DSC and TGA. The experiment results indicate that polymerization is affected by temperature and time. Under a certain polymerization temperature the yield of linear polymer is varied between 20% ~ 40% . The resulting inorganic polymer has a excellent solubility in common solvent and high thermal stability.
