  • Difluoroamino oxetanes and polymers formed therefrom for use in energetic formulations
    Patent number: 5420311
    Abstract: This invention relates to novel oxetanes containing neopentyl difluoroamino groups. More specifically, mono- and bis-(difluoroaminomethyl)oxetanes are synthesized. These compounds are prepared by the direct fluorination of blocked neopentyl amines. These mono- and bis-(difluoroaminomethyl)oxetanes can be polymerized to form homopolymers and copolymers with load beating polyether backbones and highly energetic pendant groups. The homopolymers and copolymers of the present invention are useful as energetic binders in high-energy formulations, such as propellants, explosives, and gasifiers.
    Type: Grant
    Filed: June 24, 1993
    Date of Patent: May 30, 1995
    Assignee: Aerojet General Corporation
    Inventors: Thomas G. Archibald, Gerald E. Manser, John E. Immoos
