Title: anionic polymer Long Title: IUPAC Gold Book - anionic polymer DOI: 10.1351/goldbook.AT07198 Status: current Definition Polymer composed of negatively charged macromolecules and an equivalent amount of counter-cations. Notes 1) If a substantial fraction of constitutional units carries negative charges, then an anionic polymer is a polyelectrolyte. 2) The term anionic polymer should not be used to denote a polymer prepared by anionic polymerization.
