Abstract: 3'-Allyldibenzo-18-crown-6,prepared from 3-allylcatechol and 1,2-bis(β-(β′-chloroethoxy)-ethoxy)benzene,was subjected to hydrosilylation by methyldichlorosiloxane,followed by polycondensation with hydroxy-terminated polydimethylsiloxane to give a linearpolysiloxane with pendant crown ether moieties.The transport properties of sodium,potas-sium,and ammonium salts throtigh a bulk liquid membrane system usiiig this polysiloxane asa carrier have been investigated.

Key words: rown ether, polysiloxaiie, ioiiophore, liquid membrane
