Permeation parameters were obtained for various commercial polyimide/Teflon FEP laminates. Permeation coefficients, predicted from data obtained separately on each component of the laminate, match closely those found experimentally. The diffusion and solubility coefficient values, which are not amenable to such predictions, demonstrate that closely similar permeation coefficient values may be obtained from widely different diffusion and solubility coefficient values.
