Multilayer diffusion behavior and the swelling effect of 1-butene and propylene in dry AgNO(sub 3)-doped perfluorocarbon type ion-exchange membranes

An explanation of the transport mechanism of 1-butene and propylene through dry AgNO(sub 3)-doped PSM membranes is detailed. This is achieved by multilayer diffusion together with the swelling of the surrounding polymer pendant side chains by the sorbed alkene molecules.
