The effect of CuO, Fe₂O₃, carbon black (CB), PbCO₃, Bi₂O₃ and (NH₄)₂Cr₂O₇ on the thermal decomposition properties of P(BAMO/AMMO) energetic binder was investigated by TG and DSC. Results show that the six burning rate catalysts make the initial decomposition temperature of P(BAMO/AMMO) binder shift downwards and the exothermic decomposition reaction of azide groups advance, and the exothermic decomposition reaction of binder is promoted, in which, CB and PbCO₃ make the initial decomposition temperature of the binder shift 8.3 ℃ and 24.2 ℃ downwards at a heating rate of 10 ℃·min^-1 , respectively. CuO, Fe₂O₃, PbCO₃ and (NH₄)₂Cr₂O₇ make the apparent decomposition heat of azide groups in P(BAMO/AMMO) binder increase by 0.05, 0.09, 0.10 kJ·g^-1 and 0.06 kJ·g^-1, respectively, whereas CB and Bi₂O₃ make the apparent decomposition heat of azide groups decrease.
