Abstract 1. A PROCESS FOR MANUFACTURING A GAS-PRODUCING COMPOSITION CONTAINING BOTH A CYCLIC POLYMETHYLENE-POLYNITRAMINE HIGH EXPLOSIVE AND AMMONIUM PERCHLORATE, AND COMPRISING THE STEPS OF COATING THE SAID HIGH EXPLOSIVE WITH A VISCO-ELASTIC BINDER HAVING A VISCOSITY BETWEEN 250,000 AND 7,000,000 POISES AT 25*C. SELECTED FROM THE GROUP CONSISTING OF POLYISOBUTENE AND POLYPROPENE TO FORM A MIXTURE OF THE HIGH EXPLOSIVE AND BINDER, FORMING SEPARATELY A MIXTURE OF AMMONIUM PERCHLORATE AND SAID VISCO-ELASTIC BINDER, AND FINALLY MIXING TOGETHER THE TWO SO FORMED MIXTURES IN PREDETERMINED PROPORTIONS TOGETHER WITH FURTHER BINDER, IF NECESSARY, TO FORM A PREDETERMINED COMPOSITION.
