Polymer-bound crown ethers. I. Synthesis and complexation of polymer-bound benzocrown ethers

Abstract

Polymer-bound crown ethers were obtained by Mannich reaction of benzocrown ethers with amino polymers, polycondensation of dibenzo-18-crown-6 with acyl dichlorides, and polycondensation of benzocrown ethers with formaldehyde and aromatic compounds. Complexation reactions with potassium thiocyanate or picrate as well as with perchloric acid were used for crown ether group determination. The reaction kinetics of polymer-bound crown ethers with potassium iodide were studied.
