Abstract
Stabilized, amorphous high energetic compositions having crystallization inhibiting polymers dispersed throughout the solid composition. The compositions disclosed herein are an improvement over crystalline high energetic compositions in that such disclosed compositions are stable and possess physical properties desirable in propellant and high explosive applications.
Claims11
An energetic solid solution comprising:
- secondary high explosive wherein the amorphous secondary high explosive is cyclotetramethylene-tetranitramine (HMX), hexanitrohexaazaisowurtzitane (CL-20), and trimethylenetrinitramine (RDX) or a combination of at least two thereof, and at least one polymer selected from the group consisting essentially of poly(benzimidazolone sulfone), polyvinyl acetate, cellulose acetate butyrate, cellulose acetate, polyimide, and nitrocellulose and, wherein the secondary high explosive and polymer are present as a single-phase glassy state.
