Abstract: Gas generating compositions or propellants are provided which comprise a non-azide fuel which is a transition metal complex of an aminoarazole. Preferred transition metal complexes are zinc and copper complexes of 5-aminotetrazole and 3-amino-1,2,4-triazole, with the zinc complexes most preferred. The propellant compositions also include a conventional oxidizer, such as potassium nitrate or strontium nitrate. These compositions are useful for generating a nitrogen-containing gas for a variety of applications, especially for inflating air bags in automotive restraint systems, as well as other inflatable devices.

Abstract: Internally plasticized elastomeric binders for projectile propellants are cured polyethers containing THF, CYMMO plus BMEMO, BEEMO and/or OMMO mer units. The polyethers are fluid at room temperature and are miscible with nitrate ester plasticizers. Propellant binders prepared from these polyethers are curable, have low T.sub.g 's, good mechanical properties, and I.sub.sp 's comparable to PEG-based binders.

Abstract: A low cost infrared flare composition which uses a high molecular weight fluorinated resin, a low molecular weight fluorinated resin, a polymerizing solvent, and an initiator to form a binder which is combined with a reducing agent to yield a composition readily processable into various grain shapes and varying degrees of hardness thereby providing more consistent burning rates.
