Polymers composed of macromolecules consisting of zwitterionic repeating units (structure-based polymer class name).
Notes:
- Polyzwitterions are mostly polyelectrolytes, since their zwitterionic groups are usually located in pendant groups (not in main-chain groups).
- Polybetaines are a subclass of polyzwitterions.
- Unlike polyampholytes, polyzwitterions have anions and cations in the same monomeric unit.
- From the chemical structure point of view, a zwitterionic polymer is an ampholytic polymer containing ionic groups of opposite sign, commonly in the same pendant group.
