Recent progress in the field of zwitterionic polyelectrolytes is reviewed. This class of
polyelectrolytes is only five decades old, since the first synthesis was in 1952 …

The partitioning behavior of two model proteins in poly (ethylene glycol)(PEG)–poly (acrylic
acid)(PAA) aqueous two-phase systems has been studied. The effect of polymer molecular …

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 …

Two novel cross-linked anionic polyelectrolytes (CAPE) I and II containing pH-responsive
amino acid residues have been synthesized via cycloco-and ter-polymerization of a …

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

Dopamine hydrochloride was converted to monomer N, N-diallyldopamine hydrochloride
[(3, 4-(HO) 2 C 6 H 4 CH 2 CH 2 NH+(CH 2 CHdouble bondCH 2) 2 Cl−](I). Polymerization …

A diallyl amine salt monomer bearing a β-CD substituent was cyclopolymerized for the first
time. The reaction of 6-O-toluenesulfonyl-β-cyclodextrin [(C 6 H 10 O 5) 6-(C 5 H 7)]-CH 2 …

The effect of pH and salt concentration on the partitioning behavior of bovine serum albumin
(BSA) and cytochrome c in an aqueous two‐phase polymer system containing a novel pH …

Aqueous two-phase systems (ATPSs) are potential bioseparation techniques in industry.
However, a key problem is that aqueous two-phase systems could not be effectively …
