Complexing of polymer-bound crown ethers with sodium salts in aqueous solution

It has been established that polymer-bound crown ethers L₁ and L₂ are effective sorbents for sodium salts in aqueous solution; the manner in which sodium salts are bound by these ligands differs. Complex compounds of immobilized macrocyclic polyether L₁ with sodium salts have been shown to have the properties of reversible anion exchangers.L. V.
