Synthesis and characterization of azido plasticizer

In order to get a good compatibility with azidopolymers, plasticizers are r equired with a similar chemical structure. The energetic plasticizers EGBAA , DEGBAA, TMNTA and PETKAA were synthesized and characterized. They are liq uid and the glass-transition temperatures are between -70.8 degrees C and - 34.1 degrees C. The differential scanning calorimetry (DSC) analysis shows an acceptable thermal stability for practical applications. The infrared sp ectrum shows distinctly the functional groups C-N-3, eater, carbonyl and ni trate. The elemental analysis and NMR agree with the molecular structures. As a practical example, EGBAA was combined with the energetic binder Poly-N immo. The viscosity, glass-transition point and stability of 50% mixtures w ere investigated.
