Abstract
Abstract A double-base granular propellant consisting mainly of nitroglycerine and nitrocellulose, said nitrocellulose being formed into a three-dimensional structure by the crosslinking reaction of a polyfunctional isocyanate, is disclosed. The propellant is superior to conventional double-base granular propellant in the shooting performance, and can be obtained by a simple solvent-granulation process.
