Preparation, Characterisation and Cookoff Behaviour of Booster Compositions Prepared from RDX and Acrylic or Ethylene-Vinyl Acetate Dispersions
Abstract
A range of potential booster explosives has been prepared using RDX and commercially available acrylic and ethylene-vinyl acetate dispersions. The dispersions were coagulated in hot aqueous slurries of RDX by electrolyte addition and the use of thermal coagulation aids, a process compatible with existing Australian production plant and methods. Generally the polymer coatings on the RDX crystals were porous and the precipitated particles had not coalesced to form polymer films. In these cases the compositions were no less sensitive to impact than RDX. Several softer polymers gave effective coatings and desensitized the RDX. Film formation was enhanced using plasticizers and flow properties were improved by applying an additional coating of zinc stearate. Vacuum thermal stability in most cases was excellent. Australia.
