摘要：
The temperature dependences of the heat capacities of 5-vinyltetrazole and poly-5-vinyltetrazole were measured by adiabatic vacuum calorimetry over the temperature range 6-(350–370) K with errors of ∼0.2%. The results were used to calculate the thermodynamic functions of the compounds, Cp∘, H∘(T) - H∘(0), S∘(T), and G∘(T) - H∘(0), over the temperature range from T → 0 to 350–370 K. The energy of combustion of 5-vinyltetrazole and poly-5-vinyltetrazole was measured in an isothermic-shell static bomb calorimeter. The standard enthalpies of combustion ΔcH∘ and thermodynamic characteristics of formation ΔfH∘, ΔfS∘, and ΔfG∘ at 298.15 K and p = 0.1 MPa were calculated. The results were used to determine the thermodynamic characteristics of polymerization of 5-vinyltetrazole over the temperature range from T → 0 to 350 K.
