Notes:
The diffusion of gases through glassy polymers is studied and the effective diffusion coefficient Deff is represented as the result of the superposition of two fundamental mechanisms, namely slipping and hopping. Deff is calculated by a two-point correlation method. Comparisons are made with experimental data of Meares for diffusion coefficients of Kr, O2, He, and A in poly(vinyl acetate) in the glassy state. Good fits are obtained and yield significant parameters.
