    摘要: Chemical coolant formulations for treating the hot gas formed by an airbag inflator and corresponding methods of inflating an airbag cushion are provided. The chemical coolant formulations include a first ingredient which, when contacted by the hot gas, endothermically decomposes to form a cooling gas and a solid slag component and a second ingredient which, when contacted by the hot gas, forms a liquid slag component. The solid and liquid slag components cooperate to form a unified slag mass.

    摘要: Binders for propellants for the like comprise elastomers which are based on block copolymers in which a pair of poly(caprolactone) blocks flank a central hydroxyl-terminated poly(butadiene) block. The block polymers are cured with isocyanates through the OH termini of the poly(caprolactone) blocks. The elastomers have inherent energies and other characteristics intermediate those of PCP and HTPB and have good compatibility with nitrate ester plasticizers.

    摘要: A prepolymer for use in preparing a binder for low vulnerability gun propellants. The condensation of an alkynediol and formaldehyde produces a prepolymer which is cured with a polyisocyanate. The resulting binder can be combined with 1,3,5,7-tetramethylenetetranitramine (HMX) or 1,3,5-trimethylenetrinitramine (RDX), and is readily extruded as multi-perforated propellant grains, the extruded material having a greatly reduced tendency to slumping, and an enhanced mass impetus value.
