Abstract
Water-soluble protein is coated onto particles of nitramines by making a rry of nitramine powder in a water solution of the protein and removing the water by evaporation or by filtration after previously precipitating the protein by addition of ethanol. The protein coating acts as a bonding agent to enhance the bond strength between propellant binders and the nitramine particles, resulting in substantial enhancement of desirable propellant properties.
