“…The intervention of 4 C, C bond between the opposite charges, and the larger distance in between them as well as steric congestion, prevent the ampholytic motifs from coiling up to demonstrate intragroup interactions. In an extended conformation, the dipole moment of the ampholytic motifs increases, thereby increasing its hydrophilicity and solubility 5,38–40 …”

Ammonium persulfate‐initiated cyclopolymerization of maleic acid (HO2CC=CCO2H) (MA) with diallylamine (–NR2, R = CH2 = CH‐CH2) derivatives (DADs): R2NH+CH2CO2− (I), R2NCH2CO2−Na+ (II), R2NCH2CO2Et (III), R2NH+(CH2)3CO2− (IV), R2N(CH2)3CO2Et (V), R2NH+(CH2)3SO3− (VI) and R2N(CH2)3SO3−Na+ (VII) gave a series of new pH‐responsive alternate copolymers: –[(DAD‐alt‐MA)]n– VIII‐XIV, respectively. Homopolymers XV and XVI of the corresponding monomers IV and V·HCl were also synthesized. The evaluation of the synthesized polymers as potential antiscalants in reverse osmosis (RO) plants was examined. An effective scale inhibitor must arrest the formation of scale for a residence time (≈15 min) of feed water in the RO chamber. R2NH+(CH2)3CO2− (IV)‐alt‐MA copolymer XI at a concentration of 5 ppm imparted 99% scale inhibition for 360 min, while at 2.5 and 1 ppm concentrations, the CaSO4 scale inhibitions were found to be 99% and ≈ 100% during 120 and 20 min, respectively, at 40°C. Homopolymers XV and XVI, at a 20‐ppm concentration, demonstrated ≈ 95% efficiency in inhibiting mild steel corrosion in 1 M HCl. In some important oilfield applications, requirement of simultaneous scale and corrosion inhibition make these polymers potential candidates for desalination and oilfield applications.

“…Cyclopolymerization of zwitterionic monomer 194 produced the unstable polysulfobetaine PZ 195 in low yields, whereas copolymerization with SO 2 produced the water‐insoluble stable copolymer 197 in high yields (Scheme 30). [99] PZ 197 was soluble in the presence of salts, such as NaCl and KI.…”

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.
