Time development of diffusion-limited oxidation profiles in a radiation environment

We have previously presented a quantitative model that combines diffusion and kinetic expressions with chemical/mechanical property relationships to predict the time development of diffusion-limited oxidation profiles in polymers. This model was shown to be applicable to thermal aging environments and should be generally applicable to environmental stresses for which total damage to the material is directly proportion to total exposure time. In this work, we use a fluorocarbon elastomer to demonstrate applicability-of the model to ionizing-radiation environments. (C) 1997 Elsevier Science Ltd.
