Abstract
Sorption equilibria and permeation rates for oxygen and carbon dioxide in polycarbonate membrane were measured at different temperature betw een 30 and 60-degrees-C and at pressures up to 2.5 MPa. The pressure d ependence of mean permeability coefficient to oxygen obeyed the conven tional dual-mode mobility model, whereas that to carbon dioxide follow ed a modified dual-mode mobility model with concentration-dependent di ffusivities, as that of polystyrene to the same gas did.
