ABSTRACT:
Gem-difluoroamino compounds are employed as a partial or complete replacement for TVOPA (trisvinoxypropyl adduct), tris-1,2,3-[bis(1,2-difluoroamino)-ethoxy]propane, in accordance with the nomenclature established by the International Union of Pure and Applied Chemistry. A partial or complete replacement of the vicinal-(1,2-)difluoroamino plasticizer of a difluoroamino-based propellant with its structural isomer or a related structural isomer, namely, a geminal-(1,1-)bis-difluoroamino compound has resulted in two beneficial effects, namely, a marked reduction in pressure exponent and an enhancement of the burning rate of the propellant. Representative of the geminal compounds are the compounds identified as SYEP and SYPO and further identified by the following structural formulas and chemical nomenclatures:
SYEP
