Abstract
The present invention relates to modified propellant compositions of either single or multiple based type which are obtained by resolvating a conventional, previously solvated nitrocellulose-based granular propellant with a solvent such as methyl ethyl ketone followed by the addition of glycerine to replasticize the composition and create a slurry. Upon evaporation of the solvent, a waterproof and self-supporting explosive composition is produced which is extremely stable and resistant to impact, friction and static discharge.
