This review summarizes mostly the literature data accumulated during the last decade on
betaine-type polyampholytes. Synthetic pathways to polybetaines consisting of radical …

Hydrophobic cross-linked polyzwitterionic acid (HCPZA) containing long chain (C 18)
hydrophobes and residues of a glutamic acid having unquenched nitrogen valency was …

This article reviews the synthesis of polyzwitterions (PZs)(poly‐carboxybetaines,‐
phosphonobetaines, and‐sulfobetaines) having multiple pH‐responsive centers. The …

The alternate cyclo-copolymerization of diallylammonioethanoate [(CH 2= CHCH 2) 2 NCH
2 CO 2−] and maleic acid in the presence of a cross-linker afforded a novel pH-responsive …

Surfactants are among the most versatile and widely used excipients in pharmaceuticals.
This versatility, together with their pH-responsive membrane-disruptive activity and low …

In this work, a unique cross-linked polyzwitterion/anion with an aspartic acid residue was
synthesized via butler's cyclopolymerization protocol involving N, N-diallylaspartic acid …

Hydrophobically substituted diallylamines bearing a hexyl, dodecyl, or octadecyl chain were
synthesized and homopolymerized as hydrochlorides. Copolymerization of the diallylamines …

t-Butyl hydroperoxide-initiated cycloterpolymerization of diallylaminoaspartic acid
hydrochloride [(CH2CHCH2) 2NH+ CH (CO2H) CH2CO2H Cl−](I), maleic acid …

Solution properties of alternating polyampholytes based on N, N‐dimethyldiallylammonium
chloride and maleic acid as well as N, N‐dimethyldiallylammonium and maleamic acid …

Abstract The zwitterionic monomer, ethyl 3‐(N, N‐diallylammonio) propanephosphonate,
was cyclopolymerized in aqueous solutions using t‐butylhydroperoxide or ammonium …
