    摘要: An effective neutral polymeric bonding agent (NPBA) is disclosed for a polar filler such as crystals of a nitramine (HMX or RDX, for example) dispersed in a polar binder, such as energetic binders containing nitro- and nitrato-plasticizers. The exceptional strength of the propellant composite of this invention is derived from a NPBA tailored to conform to criteria found to take advantage of the surface and absorption properties of the system so as to inculcate such strength. In particular, an interpolymer of acrylonitrile, methylacrylate and hydroxyethylacrylate can be tailored to provide a NPBA for a submix of a OH-terminated prepolymer and polar nitro- or nitratoplasticizers, such as nitroglycerine, which have solubility parameters in about the same range. Typically the submix includes HMX, RDX, ammonium perchlorate and the like along with fuel particles such as aluminum, boron, and the like.
