摘要：Asymmetric gas separation membranes of materials having selective
permeation of at least one gas of a gaseous mixture over that of one or more remaininggases of the gaseous mixture, exhibit significantly improved permeation selectivities forthe at least one gas when the asymmetric membrane is contacted on one or bothsurfaces with an effective amount of a Br nsted-Lowry acid. The improved asymmetric gasseparation membranes, process for producing the improved membrane, and processesutilizing such membranes for selectively separating at least one gas from a gaseousmixture by permeation are disclosed.
