摘要：

In permeation through polymeric membranes, plasticizing of the film by the permeates reduces membrane selectivity. This effect is evaluated as the solubility difference of a permeate between its pure state and the state where it is mixed with another compound. The solubilities of methane, ethylene, nitrogen, and methane-ethylene mixture in polyethylene, polypropylene, and Teflon, the permeabilities of methane and ethylene through polyethylene, and the separation of methane-ethylene mixture by permeation through Teflon and cellulose acetate films were determined and discussed. © 1969, American Chemical Society.
