The thermal behavior, mechanism and kinetic parameters of the exothermic decomposition reaction of 3,3-bis(azidomethyl)oxetane/tetrahydrofuran (BAMO/THF) copolymer in a temperature-programmed mode have been investigated by means of DSC, TG-DTG, fast and lower thermolysis/FTIR and TG-MS. The reaction mecha-nism was proposed. The apparent activation energy and pre-exponential constant of exothermic decomposition re-action of the compound at 0.1 MPa are 167.04 kJ昺ol-1 and 1014.41 s-1, respectively. The corresponding critical temperatures of thermal explosion obtained from the onset temperature Te and the peak temperature Tp are 223.20 and 245.78 ℃, respectively. The kinetic equation of the exothermic decomposition process of BAMO/THF at 0.1 MPa could be expressed as: ()[]24315.1922.009×10/d10ln1edTTaa-=--
