ON THE CARBON 1S PHOTOELECTRON-SPECTRUM OF CELLULOSE

A series of samples of cellulose having a range of crystallinity have been prepared from a highly crystalline variety. Crystallinity values of these specimens have been determined by X-ray diffractometric techn ique. Carbon 1s photoelectron spectra of these specimens have been dec onvoluted and the contributions arising out of different oxygen functi onalities have been separated. The results obtained show a regular inc rease in extraneous hydrocarbon contaminant concentrations with the de crease in crystallinity fractions present in the specimens studied.
