Abstract
Propellant compositions have an elastomeric binder formed by curing a hydroxyl-terminated polyether or polyester prepolymer with cis-,cis-1,3,5-tri(isocyanatomethyl) cyclohexane. The propellant compositions also include high-energy particulates and high-energy plasticizers. The use of cis-cis-1,3,5-tri(isocyanatomethyl)cyclohexane increases the energy of the propellant per binder weight and in several cases substantially improves the mechanical characteristics of the propellant composition.
