Polymer composed of negatively charged macromolecules and an equivalent amount of counter-cations.
Notes:
- If a substantial fraction of constitutional units carries negative charges, then an anionic polymer is a polyelectrolyte.
- The term anionic polymer should not be used to denote a polymer prepared by anionic polymerization.
