Abstract

The glycidyl azide polymer produced by hydrolysis of glycidyl chloride followed by reaction with sodium azide is employed in a crosslinked composite-modified double-base propellant composition both in the casting powder portion and casting solvent portion as a superior replacement for nitroglycerin in each portion specified. The crosslinked composite-modified double-base propellant composition is characterized by having a greater safety in handling, reduced sensitivity to detonation, higher burning rate, higher specific impulse, and improved mechanical properties as compared with a like composition containing nitroglycerin in the casting powder and the casting solvent portions.
