  • Energetic binders for plastic bonded explosives
    Patent number: 4988397
    Abstract: An energetic uncured binder composite mixture comprising(1) a hydroxy-terminated polyfluoroformal prepolymer of the general formulaHOCH.sub.2 (CF.sub.2).sub.n CH.sub.2 [OCH.sub.2 OCH.sub.2 (CF.sub.2).sub.n H.sub.2 ].sub.m OHwherein 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 isbis(2,2-dinitropropyl)formal,bis(2,2-trinitroethyl)formal,bis(2-fluoro-2,2-dinitroethyl)formal,bis(2,2-difluoro-2-nitroethyl)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.
