Part of the Polymer Science and Technology book series (PST, volume 6)

Abstract

Although the existence of linear correlations between the logarithms of the pre-exponential factors (Log Do) and the activation energies (ED) for the diffusion of simple gases in elastomers has long been recognized [1, 2], there has not been any detailed analysis of the validity of the correlations reported in the literature.
