2. An article of manufacture useful as a gas generator and comprising a container having an outlet and supported and adapted to burn within said container and adhered to the walls of said container a mixed, shaped and cured composition of matter characterized by generating large volumes of gas on combustion and, except for minor amounts of compounding ingredients, consisting essentially of from about 70 to 87% by weight of finely-divided dried ammonium perchlorate, from about 0.5 to 5.0% by weight of at least one high surface area finely-divided essentially anhydrous inorganic silicon and oxygen-containing burning rate modifier selected from the group consisting of silicon monoxide, fume silica, arc silica and silicon oxyimide, and the balance a combustible organic elastomeric polymeric binder selected from the group consisting of a cured polyesterurethane of an organic diisocyanate and a hydroxyl terminated polyester of a dibasic acid and a glycol and a polymer comprising predominantly linear carbon chains cured through at least a portion of its combined curable acid groups selected from the class consisting of COOH, SO.sub.3 H, SO.sub.2 H and PO.sub.3 H.sub.2 radicals.
A composition of matter useful in generating large volumes of gas on combustion and, except for minor amounts of compounding ingredients, consisting essentially of from about 70 to 87% by weight of finely-divided, dried ammonium perchlorate, from about 0.5 to 5.0% by weight of at least one high surface area finely-divided essentially anhydrous inorganic silicon and oxygen containing burning rate modifier selected from the group consisting of silicon monoxide, fume silica, arc silica and silicon oxyimide, and the balance a combustible organic elastomeric polymeric binder selected from the group consisting of a cured polyesterurethane of an organic diisocyanate and hydroxyl terminated polyester of a dibasic acid and a glycol and a polymer comprising predominantly linear carbon chains cured through at least a portion of its combined curable acid groups selected from the class consisting of COOH, SO.sub.3 H and PO.sub.3 H.sub.2 radicals.

The method of making a composition useful in generating large volumes of gas on combustion which comprises mixing together to obtain a thorough dispersion from about 70 to 87% by weight of dried ammonium perchlorate, from about 0.5 to 5.0% by weight of at least one high surface area finely-divided essentially anhydrous inorganic silicon and oxygen-containing burning rate modifier selected from the group consisting of silicon monoxide, fume silica, arc silica and silicon oxyimide, and, as the balance except for minor amounts of compounding ingredients, a combustible organic elastomeric polymeric binder selected from the group consisting of a polyesterurethane of an organic diisocyanate and a hydroxyl terminated polyester of a dibasic acid and a glycol and a polymer comprising predominantly linear carbon chains having combined curable acid groups selected from the class consisting of COOH, SO.sub.3 H, SO.sub.2 H and PO.sub.3 H.sub.2 radicals, shaping the resulting dispersion and curing the same, the temperature during mixing, shaping and curing being at least 100.degree. F. below the auto-ignition point of the composition.
