A rigorous test of theoretical treatments for diffusion-limited oxidation was completed by conducting an extensive series of radiation-initiated oxidation experiments on a commercial EPDM material. Oxidation profiles were monitored from density changes; profiles were obtained versus sample thickness, radiation dose rate and surrounding oxygen partial pressure. The resulting profile shapes and magnitudes could be quantitatively fit with a two-parameter theoretical treatment based on oxidation kinetics containing unimolecular termination reactions. The theoretical parameters derived from fitting allowed quantitative confirmation of a governing theoretical expression relating these parameters to independently measured values for the oxygen consumption and permeation rates.
