  • Propellant with thermoplastic elastomer binder composed of macromolecular block with alkoxyalkyl acrylate termination
    Patent number: 4997498
    Abstract: Thermoplastic elastomers made by copolymerizing macromolecular monomers with alkoxyalkyl acrylates serve as binders for solid propellants which binders have high burn rates and increased insensitivity over conventional binders. The preferred alkoxyalkyl acrylate is methoxyethyl acrylate.

  • Curing process for the manufacture of thermoplastic elastomer binders
    Patent number: 4986940
    Abstract: 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.
