Method of preparing castable, insensitive energetic compositions

摘要

Energetic materials exhibiting low sensitivity comprise a solid solution of nitroaliphatic oxidizer, preferably trinitroethyl derivatives, in a plasticized thermoplastic elastomer such as a block copolymer of polystyrene and polyacrylate plasticized with dioctyl adipate. The energetic material is prepared by forming molten plasticized elastomer and then incrementally dissolving the oxidizer in the molten binder.
