Energetics of BAMO

Abstract

3,3‐Bis(azidomethyl)oxetane (BAMO) is a typical energetic azide polymer containing two N3, bonds in the molecular structure. Since BAMO is a solidified polymer at room temperature, a liquid BAMO copolymer with tetrahydrofuran (THF) was synthesized in order to gain energetic binders for solid propellants. Various types of experiments were carried out to elucidate the decomposition and combustion processes of BAMO polymer, BAMO/THF copolymer, and crosslinked BAMO/THF copolymer. The heat produced by the decomposition is caused by the bond breakage of ‐N3 to produce N2, gas. The burning rate characteristics of crosslinked BAMO/THF copolymer depend largely on the mole fraction ratio of BAMO and THF.

Synthesis and Characterization of Poly(3‐azidomethyl‐3‐methyl oxetane) by the Azidation of Poly(3‐mesyloxymethyl‐3‐methyl oxetane)

“…It can be seent hat the thermal decomposition process of PAMMO includedt wo steps, which was consistentw ith the previous studiest hat the two-step thermald ecomposition process was observed for azido polymers [15][16][17][18][19]. The first step from 220 8Ct o2 80 8Cw as mainly corresponding to the decomposition of the azidog roup, whichw as the least stable group in the compound.T he weight loss percentage of this step was about 30 %a nd it was consistent with the mass contento fn itrogen in PAMMO, which confirmed once more the thermal decomposition of azido group in the first stage.…”

Advances in science and technology of modern energetic materials: An overview

“…Emergence of novel propellants having unique combination of high energy and low vulnerability has led to development of energetic polymers [147][148][149][150][151]. Prepolymers having exothermically decomposing azido groups or oxygen-rich facile nitro/nitrato groups offer formulations with superior performance potential at relatively lower solid loading.…”

Surface Coating of Nitroamine Explosives and Its Effects on the Performance of Composite Modified Double-Base Propellants

“…More recently, much interest has been generated on how to improve the propellant's overall properties. The main approaches include the following: 1) using advanced binders or plasticizers, such as glycidyl azide polymer [6,7] or 3,3diazidomethyloxetane [8,9]; 2) improving the particle properties of the solid fillers by reducing the particle size [10][11][12][13] or changing the particle morphology [14][15][16]; and 3) optimizing the propellant's formulation and charge structure [17,18]. An acutely popular method to improve the propellant properties is to coat its sensitive fillers.…”
