概要

Pressure effect on the diffusion of rigid aromatic and flexible linear aliphatic molecules in polymers was described. The results were discussed on the basis of the activation volume for the diffusion, ΔV≠. ΔV≠ was analysed in terms of the intrinsic molecular volume, the length of the chain, the degrees of swelling and crystallinity of the polymer and the solvation of the diffusant. The temperature dependence of. ΔV≠, the pressure dependence of the activation energy for the diffusion and the pressure dependence of de Genne's scaling rule for the diffusion of chain molecule were also discussed.
