Polymeric and immobilized crown compounds, material for ion separation

Article abstract of DOI:10.1016/S0040-4020(96)01072-1

We describe the synthesis of ionoselective polymers bearing different pendant crown ethers. The synthesis was applied to various macrocycles. We discuss the influence of macrocyclic cavity size and rigidity of the polymers on the extraction behavior. Accessibility of active sites can be achievied with immobilized functionalized polyurethanes chemically bound to an inorganic solid support, with no change of ionoselective properties.
