The degradation kinetics of solid rocket propellant based on a glycidyl azide polymeric binder with ammonium nitrate were determined by gas chromatographic quantitation of the headspace gases over heated samples. This approach was found to allow the determination of degradation at temperatures approaching ambient. An Arrhenius plot was constructed from the data and kinetic parameters, including activation energy and relative rates of degradation, were calculated. Two different batches of propellant were found to exhibit similar degradation kinetics, although one was estimated to have a shorter service life based on the relative volumes of gases liberated.
