Synthesis of Thermally Stable High Density and High Energy Plasticizers

Abstract

The primary objective of this research program was the synthesis of thermally stable, high density, and high energy plasticizers for new high energy polyether binders of interest to the Air Force. Initially the synthesis of three specific nitro-difluoramino-ether plasticizers was studied, but difficulties in synthesis and poor yields made their preparation impractical. The research effort was then redirected toward the synthesis of a series of nitrodifluoramino-formal plasticizers which resulted in the synthesis of SYFO, bis(5-fluoro-5,5-dinitro-2,2-bis(difluoramino)pentyl) formal. In overall properties, SYFO has outperformed all other energetic plasticizers known. Results of tests to date show that SYFO has the required high energy and density, low volatility, and thermal and chemical stability. In addition, SYFO imparts excellent properties to propellants formulated with it, and results in thermally stable propellants which heretofore have not been possible.
