Nature of the Diffusion Process in Rubber


IT is known1,2, that silica-gas diffusion systems exemplify a type of non-specific activated diffusion process, as opposed to the specific type of diffusion system such as hydrogen-palladium. It seemed that the diffusion of gases through other glass-like materials such as some organic membranes, for example, rubber, might offer further examples of non-specific activated diffusion. The data needed to test this hypothesis were available in papers by Edwards and Pickering3, and by Dewar4. Graham5 first noted the large temperature coefficient of the diffusion process through rubber, and that the diffusion velocities had no connexion with the molecular weights.
