In this contribution, the synthesis and characterization of novel ion‐exchange blend membranes which contain the SO 3 Ag group for the application in the perstractive separation of alkene–alkane mixtures, where the Ag + ion serves as facilitated transport site for the alkene via formation of a pi complex with the alkene double bond, is presented. In this part of the article, the transport properties of the following blend membrane types are described: (1) acid–base blend membranes of ortho‐sulfone‐sulfonated polysulfone (PSU) with ortho‐sulfone‐diaminated PSU; (2) blend membranes of ortho‐sulfone‐sulfonated PSU with unmodified PSU; (3) blend membranes of ortho‐sulfone‐sulfonated PSU with ortho‐sulfone disilylated PSU. © 1999 John Wiley & Sons, Inc.
