초록

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.

대표
청구항

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.
