Effusion mass spectrometeric investigation of BAMO, AMMO, AZOX and GAP yielded primary decomposition of N2 release at approximately 120 C and Ea values of 170 - 180 kJ mol-1 43-43 kcal mol-1. The 50-50 copolymer of BAMO-BNMO decomposes initially through the nitrato constituent at approximately 100 C followed by the azide decomposition. The thermal degradation mechanism for BEMO appears to be a stepwise breaking of the ethoxy-methyl bonds followed by the stripping of the methylene groups. BFMO is stable to temperatures greater than 200 C with initial decomposition products of HF, with considerable depolymerization occurring. The major decomposition product of the NSWC novel nitramine, C6H8N8012, is the eight-membered nitramine ring less two N02 molecules, molecular weight 292. The decomposition product is stable in the gas phase at 300 C.
