Abstract: The enthalpic relaxation and the time temperature superposition principle of some energetic and related materials at low temperature were investigated by differential scanning calorimeter(DSC).Based on the relationship between glass transition temperature and heating rate,the equations used to calculate the viscoelastic coefficients in WLF equation were derived.The viscoelastic coefficients of ten systems were calculated,and the results indicated that the viscoelastic coefficients can be obtained by DSC.
