Sorption isotherms and steady state permeabilities for water have been measured at 40°C for polyethersulphone, polysulphone, phenoxy polymer, and polyethersulphone–phenoxy blends. The pressure dependence of the permeability in all cases was weak and the permeability of phenoxy polymer is an order of magnitude smaller than that of polyethersulphone and polysulphone. The dependence of the permeability on blend composition is compared with an empirical expression often used to describe transport in miscible blends. The effect of phase separation on the permeability is studied briefly.
