Abstract:

Compatibility studies of LMH-1 and hydrazine continue to show no significant degree of incompatibility between LMH-1 and dry hydrazine. The off-gas generation rate of these formulations is very nearly the same as the off-gas generation rate of an equivalent amount of near LMH-1. The presence of water in the hydrazine does substantially increase the initial off-gas generation rate of LMH-1hydrazine formulations, presumably due to reaction of the water with LMH-1. Water at very low level was found not only to affect the compatibility of the system, but also to contribute to changes in the physical properties of the gels. The same effects have been observed with emulsions. Because of good stability, compatibility and physical properties, the prime candidates for LMH-1 heterogeneous emulsion systems are those prepared with oleyl sarcosine derivatives. Incompatibility of imidazoline derivatives with the heterogeneous system eliminated those emulsifiers from further consideration. Gelling agents have been selected for formulations into LMH-1 heterogeneous systems on the basis of polymeric structure. Lightly cross-linked ammonium polyacrylates of extremely high molecular weight gave cohesive gels which were only slightly adhesive and included LMH-1 within the gel structure. Author
