Abstract: Two simultaneous devices of the fast thermlysis reaction cell (gas reaction cell ) in situ in conjunction with rapid scan fourier transform infrared spectroscopy (RSFT IR), were the solid reaction cell in situ /RSFT IR are used to measure the gas products and condensed phase products of the thermal decomposition of the NEPE propellant binder in real time Under Linear temperature increase condition, the thermal decomposition characteristics of NEPE propellant binder was studied On the basis of the results obtained, the thermal decomposition mechanism was discussed

Key words: Polyether propellant;Propellant binder;Energetic ptasticizer;Thermal decomposition
