Abstract

Perchloric acid salts of polymeric amines of the type poly(ethylenimine), poly(propylenimine), poly(2-vinylpyridine), and poly(4-vinylpyridine) were prepared and characterized for possible use as monopropellants and additives in solid propellants. The thermal stabilities of these compounds were studied by DTA, TGA, isothermal weight loss, and ignition delay measurements. Thermal sensitivities of the polymeric salts increase with molecular weight up to a critical value, beyond which it becomes practically constant.
