The thermal decomposition data of the propellant samples were analyzed by thermogravimetric analysis (TG/DTG) at different heating rates in the temperature range of 300-1200 K. TG curves showed that the thermal degradation occurred in three main stages regardless of the plasticizer (DOA) raw material, the partial HTPB/IPDI binder and the total ammonium perchlorate decompositions. The kinetic parameters E-a (activation energy) and A (pre-exponential factor) and the compensation parameter (S-p) were determined. The apparent activation energies obtained from different methods showed a very good agreement.803-813engAP/HTPBFlynn-Wall-Ozawa's methodkinetic parametersthermogravimetric analysisArtigo10.1023/B:JTAN.0000041659.97749.feWOS:000223917700007Acesso restrito8460531302083773
