摘要: Abstract Energetic glycidyl azide polymer (GAP) was synthesized from polyepichlorohydrin (PECH) precursor. Thermal decomposition behavior of a mixture GAP and nitramine oxidizer (4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazaisowurtzitane (TEX)) investigated by using thermogravimetric analysis (TGA) differential scanning calorimetry (DSC). It found that the temperature TEX is unaffected presence in GAP/TEX mixture. Kinetics degradation studied model-free method results were compared with pure components. The study suggested kinetics controlled during initial stages conversion ( α > 0.25) whereas later (0.25 ≤ ≤ 1) are determined TEX. Mechanistic interpretation has been provided to observed activation energy dependencies combination optical microscopy (OM) Fourier transform infrared spectroscopy (FTIR).
