    Abstract: The present invention provides energetic thermoplastic elastomers which may be used as binders in propellant, explosive and pyrotechnic applications. The elastomers of the present invention are all hydrolyzable, allowing recycling of the elastomer's constituents and/or facilitating other constituents of the propellant, explosive or pyrotechnic. The elastomers of the present invention contain a first polymer, a second polymer having a repeating unit different from that of the first polymer, and a bridging group. Methods of preparing elastomers of the present invention include reaction of the first and second polymers with a dioic acid, or with an organic diisocyanate and a diol containing a formal linkage.

    Abstract: A process for synthesizing 1,5-Dinosyl-3,3,7,7-tetrakis(difluoramino) octahydro-1,5-diazocine (DNTDFD) by reacting tetrahydro-1,5-bis(4-nitrobenzenesulfonyl)-1,5-diazocine-3,7-(2H, 6H) dione with HNF2/oleum initially approximately between −5 and 0 degrees C., and allowing the temperature to rise to between 10 degrees C. and ambient temperature during said reaction to initiate difluoramination producing product DNTDFD. A 2:1 mixture of FREON® 11 refrigerant and pentane or cyclopentane, or pentane alone is used as a diluent and absorbent for the reagent difluoramine. The present invention reduces the time required to produce DNTDFD from about two weeks to one to three days and reduces the need to use relatively large quantities of FREON® 11, a compound which is damaging to the environment.
