Abstract
Abstract Novel gas-generating compositions comprising 40 to 100 weight percent aminoguanidine salts of azotetrazole of the formula: OR OF DITETRAZOLE OF THE FORMULA: Optional other components of such compositions include oxygenliberating or other gas-evolving substances which may be present in 0 to 60 weight percent of the composition. There are also disclosed pressurizing gas-actuated devices utilizing these compositions.
