| 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) formal/acetal (BDNPF/A). Disadvantages which these materials exhibit are low thermal stability due to the presence of secondary hydroxy groups (NG, BTTN), low energy (BDNPF/A, 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 bis(2,2-dinitropropyl) formal (BDNPF), bis (2,2,2-trinitroethyl) formal (TEFO), and 2,2-dinitropropyl 2,2,2-trinitroethyl formal (TNEPF). |
