Abstract: Imide functionalized polyphosphazenes (1P, 2P and 3P) have been synthesized from imide substituted m-aminophenol and then further characterized by FT-IR, NMR and GPC. The synthesized polyphosphazenes have been cured as thermally form cross linked networks. The thermal characterization of cured and uncured resins was done by DSC and TGA analysis. The DSC graph of a typical uncured resin 1P showed Tg at 490C and Tm at 1460C, it also showed Tons of curing at 2900C. The resin 1P, upon curing, showed increase in Tg upto 1220C due to cross linking. The TGA analysis of cured 1P showed onset of degradation at 2850C and maximum decomposition temperature Tmax at 4350C. The synthesized resins have also been evaluated for their rheological, morphological, isothermal ageing and water uptake properties for end use application.
