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 bearing 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.
