This invention relates to energetic binders, and, more specifically, a class of nitramine-containing polyether polymers characterized by favorable viscosity and glass transition temperature, as well as resistance to hydrolysis are prepared. The invention also claims a process for producing a polymer containing nitramine- and/or nitro- and/or fluoro-groups which comprises reacting at least one nitramine-containing diacid chloride monomer with at least one nitro- or fluoro-containing diol monomer in an anhydrous organic solvent (preferably tetrahydrofuran (THF), acetonitrile, or diethylether, although other organic solvents can be employed such as pentane, hexane, heptane, methylene chloride, dichloroethane, toluene, benzene, and the like) in the presence of a tertiary amine base at a reaction temperature of between about 0 DEG C and about 50 DEG C.
