## Abstract For a series of polymers, the spin diffusion coefficients __D__ do not scale as predicted from a simple expression based on regularly spaced nuclei. We compare __D__ for PVA and polystyrene with their side group either protonated or deuterated. For polystyrene, __D__ is considerably red

The development of a new model for the diffusion of gas molecules in glassy polymers is presented which utilizes concepts from free volume theory and relies on a dual-mode interpretation of sorptive dilation in glassy polymers. Three assumptions are made in the development of the model. First, the f
