IUPAC definition

Polyelectrolyte: Polymer composed of macromolecules in which a substantial portion of the constitutional units contains ionic or ionizable groups, or both.[1] Notes:

  1. The terms polyelectrolyte, polymer electrolyte, and polymeric electrolyte should not be confused with the term solid polymer electrolyte.
  2. Polyelectrolytes can be either synthetic or natural. Nucleic acids, proteins, teichoic acids, some polypeptides, and some polysaccharides are examples of natural polyelectrolytes.


IUPAC definition

Thermoplastic elastomer: Elastomer comprising a thermoreversible network.[2]


IUPAC definition

Superabsorbent polymer: Polymer that can absorb and retain extremely large amounts of a liquid relative to its own mass.[3] Notes:

  • The liquid absorbed can be water or an organic liquid.
  • The swelling ratio of a superabsorbent polymer can reach the order of 1000:1.
  • Superabsorbent polymers for water are frequently polyelectrolytes.


IUPAC definition

Closed structure formed by amphiphilic molecules that contains solvent (usually water).[4]

Here are some useful pages:

Many thanks to TBL

I once published an article about chirality of helices.[5]
