ABSTRACT:
A process for separating C.sub.2 -C.sub.4 alkenes from C.sub.1 -C.sub.6 alkanes comprises the presence of water vapor in the alkene/alkane feed and the use of an Ag.sup.+ -exchanged sulfonated copolymer of tetrafluoroethylene and perfluorovinyl ether having been prepared by one of several specific ion-exchange methods.
