MICROSCOPIC AND MICROCHEMICAL STUDY OF AGED SOLID PROPELLANT GRAINS.

Abstract

Chemical studies of the composition of binder in aged propellants was continued. Model urethane and urea were stable over 2 weeks in contact with various combinations of NH4ClO4, aluminum, ferric acetylacetonate, and copper chromite. Aging sites from a Polaris Cycling Unit have been separated from the aluminum and NH4ClO4 which are embedded within them. Analysis of this material has been delayed because of its insolubility in the common laboratory solvents. As the material may be a crosslinked polymer, further degradation may have to precede the analysis. (Author)
