THE DEVELOPMENT AND EVALUATION OF A HYDROCARBON BINDER FOR HIGH ENERGY SOLID PROPELLANTS.
Abstract
A series of hydrogenated polybutadienes and polyisoprenes of varying backbones and molecular weights and with dicarboxy or dihydroxy terminal groups were prepared and characterized for use as solid propellant ingredients. Simultaneously a number of epoxide, aziridine, and isocyanate curing agents were characterized especially with respect to their tendency to undergo stoichiometric curing reactions in the presence of NH4ClO4. Combinations of these prepolymers and curing agents were used to prepare binders. The binders were characterized by uniaxial tensile behavior, stress relaxation, swelling, hardness, and by aging at 100 C in wet and dry air and in dry argon. Propellants with 88% solids loading were made and similarly characterized. The data allowed the selection of an isocyanate curing system, CTI and HDI, as superior to the others tested and the selection of a saturated polybutadiene terminated with secondary hydroxy groups. This system was used to make 64 lbs of propellant which was extensively characterized. (Author)
