✦ Synopsis

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 ϩ 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-sulfonesulfonated 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.
