Mass Spectrometric Decomposition Studies on Several Azido and Nitrato Polymers, Thermal Plasticizers and Novel Nitramines.
Abstract
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.
