The utility of swelling tests in studies of highly-filled solid propellants and their corresponding binders is shown. The solubility parameters for two propellants are shown to be the same as those of the corresponding binders. The use of swelling measurements as a quality control technique for solid propellants is indicated. The proper selection of the solvent is critical for crosslink density determinations with a highly filled elastomer. The chemical changes occurring in propellant binders during high-temperature aging programs may be qualitatively explained by swelling tests and quantitatively determined by the determination of the compression modulus of swollen samples.
