chelating polymer

Polymer containing ligand groups capable of forming bonds (or other attractive interactions) between two or more separate binding sites within the same ligand group and a single atom.
Notes:
  1. Chelating polymers mostly act as ion-exchange polymers specific to ions that form chelates with chelating ligands of the polymer.
  2. See also: chelation.
