Synthesis of Energetic PrePolymers of Varying BAMO and NMMO or PGN Content and Structure

Composite propellants and explosives typically consist of solid oxidizers, metallic fuels, and rubbery binders that provide the needed mechanical properties. Most binder systems are cured by the formation of urethane linkages by the reaction of oligomeric diols with diisocyanates or triisocyanates. A variety of available diols and isocyanates enables the formulation of binders with optimum physical properties for specific systems. New energetic ingredients are being investigated that have chemical properties incompatible with the polyurethane system. An alternative cure system based in the reaction azido-terminated oligomers with polyacetylenes to form polytriazoles has shown potential of stability with these ingredients . The objective of this program is to prepare novel polymer-based polyazides for this application.
