Abstract:

The degradation of Pyromellitic dianhydride PMDA under x-ray exposure has been studied by X-ray Photo-electron Spectroscopy XPS and Fourier Transform Infrared Absorption Reflection Spectroscopy FTIRAS. The data indicate cleavage of the anhydride rings and emission of CO and CO2 molecules into the vacuum.
