Thermoplastic elastomers made by copolymerizing macromolecular monomers with alkoxyalkyl acrylates in the presence of energetic materials serve as solid propellants which have high burn rates and increased insensitivity over conventional propellants. The copolymers are prepared in situ by subjecting the mixture of monomers and energetic materials to electron beam radiation.
A method of making solid propellants from thermoplastic elastomer binders and energetic materials consisting essentially of (a) forming a blend of macromolecular monomers, prepared by anionic polymerization of one or more vinyl aromatic compounds and terminated with an acrylate or methacrylate group, and monomers selected from alkyl acrylates, alkoxyalkyl acrylates, diacrylate monomers, and mixtures thereof; (b) mixing into the above blend suitable energetic materials selected from solid oxidizers, solid fuels, a cyclic nitramines, and mixtures of these;...
