Abstract
Tactical missile propellant formulations are inherently sensitive to impact and friction stimuli. The impact and friction insensitivity of some tactical propellant formulations is improved significantly when internal conductive polymers PERCOL®292, (copolymer of a quaternary acrylate salt and acrylamide, Allied Colloids, Inc.) and VERSICON®, (Polyaniline)(Emeraldine salt), green/black powder, Monsanto Company) are added to the formulation. These two conductive polymers were evaluated in a high performance propellant formulation containing the same ingredients now being used in fielded tactical missiles. The impact and friction insensitivity of propellants containing these conductive polymers was improved thirty and sixty six percent, respectively.
