The thermal stability of propellant compositions containing triaminoguanidine nitrate and an energetic plasticizer-binder system is vastly improved by including in the composition an amount of resorcinol sufficient to provide with the plasticizer a solution which is essentially saturated or super-saturated at 25° C.

1. In a solid gas generating, rocket or gun propellant composition comprising an intimate mixture of an oxidizing agent selected from triaminoguanidine nitrate (TAGN) and mixtures of TAGN with secondary organic oxidizing agents, a liquid energetic nitrate ester or organic nitramine plasticizer, a nitrocellulose-containing binder component and a stabilizer, the improvement wherein the stabilizer comprises resorcinol, said resorcinol being employed in the liquid energetic plasticizer in an amount so as to at least essentially saturate the liquid energetic plasticizer with resorcinol at 25° C. 2. The composition of claim 1 in which the TAGN is the crystalline product obtained by dissolving TAGN in distilled water in a metal-free environment at a temperature between 20° C. and 30° C., cooling and maintaining the resulting aqueous solution at a temperature below its saturation temperature until a crystalline precipitate is formed and recovering the crystalline product. 3. The composition of claim 1 in which the plasticizer is a 1-(N-alkylnitramino)-2-nitroxyethane. 4. The composition of claim 3 in which the plasticizer is 1-(N-butylnitramino)-2-nitroxyethane. 5. The composition of claim 1 in which the plasticizer is 1-nitropiperidine. 6. The composition of claim 1 in which the oxidizing agent comprises from about 20% to about 85% by weight of the propellant composition. 7. The composition of claim 6 in which a mixture of TAGN and secondary organic oxidizing agents is employed, the TAGN comprising at least 25% by weight of the mixture. 8. The composition of claim 7 in which the binder component comprises from about 5% to about 70% and the liquid energetic plasticizer including resorcinol dissolved therein comprises about 10% to about 75%, based on the weight of the propellant composition. 9. The composition of claim 2 in which the oxidizing agent is TAGN and TAGN comprises from about 20% to about 85% by weight of the propellant composition. 10. The composition of claim 9 in which the binder component comprises from about 5% to about 70% and the liquid energetic plasticizer including resorcinol dissolved therein comprises about 10% to about 75%, based on the weight of the propellant composition.
