“…Symmetrical monomers 80 and 81 underwent polymerization to give polyzwitterion‐electrolyte (PZE) 82 and PZ 83 , respectively (Scheme 14). [70] Upon copolymerization, monomers 81 /SO 2 and 81 /(MA 4) pairs led to respective zwitterionic PZS 84 and PZM 85 . When used as an antiscalant, PZM 85 at 1 ppm provided 99 % prevention of CaSO 4 scale formation from its supersaturated solution for 40 min, which was sufficient to prevent scale fouling of desalination membranes.…”

This article reviews the synthesis of polyzwitterions (PZs) (poly-carboxybetaines, -phosphonobetaines, and -sulfobetaines) having multiple pH-responsive centers. The synthesis follows the Butler cyclopolymerization protocol involving a multitude of diallylammonium salts and their copolymerization with SO 2 and maleic acid. The PZs have been transformed into cationic-, anionic-polyelectrolytes, and polyampholytes under the influence of pH. Particular attention is given to the application of these polymers as antiscalants, mild steel corrosion inhibitors, components in constructing Aqueous Two-Phase Systems (ATPSs), and membrane modifiers. The ATPSs could be used to separate various biomolecules, including proteins. Many amphiphilic polymers incorporating a few mol % hydrophobic monomers have shown enhanced viscosities and could be suitable for applications in oil fields. The progress of applying Butler cyclopolymerization in reversible addition-fragmentation chain transfer (RAFT) chemistry has been discussed. Future works are expected to focus on RAFT cyclopolymerization to construct block copolymers.
