摘要

Permeability and diffusion coefficients of O2, He, CO2 and C4H6 were measured in water,swollen poly(vinylalcohol-co-itaconic acid) membranes having various water contents from 0.48 to 0.83. The permeability coefficients of CO2 and C4H6 were found to depend on the upstream pressure, while the permeability coefficients of O2 and He were independent of the pressure. With decreasing pressure the permeability coefficients of CO2 and C4H6 increased, and the pressure dependence became larger with decreasing water content of the membranes. A parallel permeation model based on the two states of water in the water-swollen membranes could be applied successfully to CO2 and C4H6.
