Solid energetic compositions are prepared from powdered solid components such as metallic aluminum fuel and liquid oxidizers by forming a coating of polyvinyl alcohol over the powdered solid by precipitation from a solution of polyvinyl acetate, and combining the coated particles with liquid oxidizer which will permeate and swell the particle coating, causing the particles to agglomerate into a solid rubbery mass.
A method for preparing a solid energetic composition containing solid particulate matter, an oxidizer and a binder for use as a propellant or explosive, said method comprising: (a) preparing a first dispersion of said solid particulate matter in a solution of polyvinyl acetate in a solvent in which polyvinyl acetate is soluble and polyvinyl alcohol is not; (b) adding to said dispersion a hydrolyzing agent to convert said polyvinyl acetate to polyvinyl alcohol, thereby depositing polyvinyl alcohol on said solid particulate matter to form coated particles,...
