摘要

<正> A modified method of preparing crown functionalized linear polysiloxane has beendescribed. 4’-Allyldibenzo-18-crown-6 was subjected to hydrosilylation withmethyldichlorosilane

followed by polycondensation with silanol-terminatedpolydimethylsiloxane to give the title crown functionalized linear polysiloxane. Thetransport properties of sodium

potassium

and ammonium salt through a bulk liquidmembrane system using the new type of crown functionalized linear polysiloxane as acarrier were investigated. It is worthy to point out that the carrier can be used repeatedlyat least six runs with no apparent change in the transport rate of potassium ion.
