Abstract : This patent discloses an energetic uncured binder composite mixture comprising: (1) a hydroxy-terminated polyfluoroformal prepolymer of the general formula HOCH2(CF2)nCH2-(OCH2OCH2(CF2)nCH2-)mOH wherein n is 3 or 4 and m is selected to provide a number average molecular weight of from about 1,000 to about 10,000 for the prepolymer; and (2) an energetic plasticizer which is bis(2,2-dinitropropyl)formal, bis(2,2-trinitroethyl)formal, bis(2-fluoro-2,2-dinitroethyl)formal, bis(2,2-difluoro-2-nitroeethyl)formal, 2,2-dinitropropyl 2-fluoro-2,2-dinitroethyl formal, or mixtures thereof; wherein the weight ratio of energetic plasticizer to prepolymer is from about 2:1 to about 5:1. This binder composite mixture is useful for preparing energetic plastic bonded explosives having high chemical and thermal stabilities.
