Nitrate ester of cellulose glycidyl ether (NGEC) is one kind of modified nitrocelluloses. The NGEC-modified double-base propellants were prepared by using traditional solvent-free method. The properties of NGEC modified double base propellant including mechanical, combustion, ballistic and combustion wave structure were investigated. The results show that NGEC has good thermoplastic and NGEC modified double base propellant exhibits a better processing property. Compared with NC-based propellant, NGEC modified double base propellant possesses 1.5 times higher elongation at low temperature (-40°C), stable ballistic performance and similar combustion properties and combustion waves structure. So, as an energetic thermoplastic binder instead of NC, NGEC can be used in new modified double base propellant research. Source

The thermal behavior and decomposition mechanism of nitrate glycerol ether cellulose(NGEC) were studied by means of TG/DTG, DSC and solid reaction cell in situ in conjunction with rapid-scan Fourier transform infrared spectroscopy (RFST-IR) for measuring the condensed phase decomposition products in real time. The kinetics parameters (activation energy and pre-exponential factor) and the free energy activation, enthalpy of activation and entropy of activation for decomposition reaction were computed by using the Kissinger' mothod, Ozawa's method and thermodynamic relations. Based on the characteristic temperature from the non-isothermal DSC curves, the critical temperature of thermal explosion of NGEC was estimated. Source
