Cyclopolymerization protocol for the synthesis of a new poly(electrolyte-zwitterion) containing quaternary nitrogen, carboxylate, and sulfonate functionalities

► A zwitterionic diallylammonium salt having ester and sulfonate moiety is prepared. ► Cyclopolymerization of the salt has provided a poly(anion-zwitterion) (PAZ). ► The PAZ behaved like an alternate anionic-zwitterionic polymer. ► The PAZ is used to study a polyelectrolyte to polyzwitterion transition.
