The effects of various aniline stabilizers on the thermal stability of nitrocellulose (NC) were investigated via isothermal thermal decomposition dynamics. The pressure-time curves of NC/stabilizer composites were found to have a distinct inflection point, which was not observed on the pressure-time curves of NC. The effects of stabilizers on the isothermal thermal decomposition kinetics of NC were evaluated using Arrhenius equation and model-fitting method, and the effect of stabilizers on the storage time of NC was estimated using Berthelot equation. Results showed that the activation energy of NC/MNA, NC/ENA, NC/i-PNA, and NC/n-BNA before the inflection point were 162.9, 153.3, 147.4, and 150.6 kJ mol(-1), respectively, which were significantly increased compared with that of pure NC (144.7 kJ mol(-1)). Furthermore, the time required for the decomposition extent of NC/MNA, NC/ENA, NC/i-PNA, and NC/n-BNA to reach 0.1 % were 24.9, 11.2, 16.7, and 11.2 years, respectively, at 298.15 K, which was longer than that required of NC (10.6 years). UV-vis revealed that the stabilizers were almost consumed when the NC/stabilizer thermal decomposition pressure-time curve reached the inflection point. Based on the above results, the stability order was MNA>i-PNA>ENA>n-BNA as the criterion for time of the inflection point.
