Condensation of 8‐hydroxyquinoline with formaldehyde in acid solution yielded a polymer of molecular weight ∽3300. Modification of this polymer with resorcinol resulted in improved physical properties of this material. 8‐Hydroxyquinoline‐formaldehyde polymers can be used as selective chelating ion‐exchange rains which permit separation of various cations. The polymeric metd chelates are thermally less stable than the unchelated polymer.
