Abstract

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 T_g of GAP soft segment only, with the content of crosslinker increasing, T_g 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.
