Energetic materials exhibiting low sensitivity comprise a solid solution of nitroaliphatic oxidizer, preferably trinitroethyl derivatives, in 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.
A castable, insensitive energetic composition consisting essentially of a homogenous solution of 65 to 85% by weight of energetic oxidizer solids of a polynitroalkyl substituted compound in which each poltnitroalkyl contains from 1-5 carbon atoms in a plasticized thermoplastic elastomer, the said plasticizer thereof being a C1 to C10 alkyl ester of an organic acid, said thermoplastic elastomer being a block copolymer containing both oleophilic hydrocarbon polymer segments and polar, oxygen containing polymer segments.
