A low-temperature grinding technique for the potassium bromide pressed-disk method was developed to obtain quantitative infrared spectra of propellants and propellant binders. The effects of grinding time and temperature on the intensities of infrared absorption bands were determined. The technique was applied to the study of the thermal degradation of a polyurethane propellant.
