N2 - To improve the performance of glycidyl azide polymer(GAP), trimethylolpropane(TMP) as the crosslinker, isophorone diisocyanate(IPDI) as the curing agent, glycidyl azide polymer/polyethylene glycol(PEG) dual-soft segments energetic polyurethane elastomer was synthesized. The elastomer was characterized with Fourier transform infrared spectrum(FT-IR), differential scanning calorimetry(DSC) and other means. The experimental results show that: When PEG is introduced into the elastomer, tensile strength of elastomer increases 168%, extension rate of elastomer increases 77%. Due to molecular weight of PEG soft segment is low, elastomer showes Tg of GAP soft segment only, with the content of crosslinker increasing, Tg of GAP soft segment raises from -36.85°C to -34.81°C and then drops to -40.31°C. The thermal decomposition behavior of elastomer can be divided into two sections, and the initial decomposition temperature is 183°C.
