Abstract:

Plasticizers which are commonly used in gun propellants and other energetic compositions are nitroglycerin NG, butanetriol trinitrate BTTN, metriol trinitrate METN, diethylene glycol dinitrate DEGN, and bis 2,2-dinitropropyl formalacetal BDNPFA. Disadvantages which these materials exhibit are low thermal stability due to the presence of secondary hydroxy groups NG, BTTN, low energy BDNPFA, METN, DEGN, and high vapor pressure DEGN, NG. Summary of the Invention Accordingly, an object of this invention is to provide a new energetic plasticizer. Another object of this invention is to provide an improved energetic plasticizer having a low vapor pressure. A further object of this invention is to provide an improved plasticizer having a low melting point. Yet another object of this invention is to provide an improved plasticizer which has good thermal stability. These and other objects of this invention are accomplished by providing energetic plasticizers which are binary and ternary mixtures of bis2,2-dinitropropyl formal BDNPF, bis 2,2,2-trinitroethyl formal TEFO, and 2,2-dinitropropyl 2,2,2-trinitroethyl formal TNEPF.
