“…Much creative and innovative work has been incited in the past 15 years by establishing the continuously evolving and now maturing methods of "reversible-deactivation radical polymerization" (RDRP). Similar to the revolutionary changes brought to polyelectrolyte synthesis [106], polyzwitterions have equally profited from this development. RDRP techniques offer direct access to polymers bearing zwitterionic groups with previously unthinkable features, such as predefined molar masses and narrow molar mass distributions [163,[182][183][184][185][186][187][188][189] as well as well-defined functional end groups [61,166,182,[190][191][192][193][194][195][196][197][198][199][200][201][202][203][204][205][206][207][208].…”

“…The latter aspect is probably the most striking one, and is closely connected to new synthetic methods for making polymers bearing charged groups [106]. The increasingly versatile and mature methods of the so-called controlled polymerizations [107], in particular of the "reversible-deactivation radical polymerization" (RDRP) methods [108] (which alternatively often are referred to as "controlled free radical polymerization" (CFRP), or even "living radical polymerization" (LRP)) have enormously fertilized the field [107,109,110].…”

Abstract:The structures and synthesis of polyzwitterions ("polybetaines") are reviewed, emphasizing the literature of the past decade. Particular attention is given to the general challenges faced, and to successful strategies to obtain polymers with a true balance of permanent cationic and anionic groups, thus resulting in an overall zero charge. Also, the progress due to applying new methodologies from general polymer synthesis, such as controlled polymerization methods or the use of "click" chemical reactions is presented. Furthermore, the emerging topic of responsive ("smart") polyzwitterions is addressed. The considerations and critical discussions are illustrated by typical examples.

“…They have a wide range of application from water treatment to tissue engineering 3,4 . Normally the "Click" chemistry is used as a powerful and efficient method to synthesis these systems, in this method, by carbon-hetero bond formation, polymers can be synthesized 5 . As these components in polar solvents are charged, the electrostatic interaction in these systems plays an important role 6,7 .…”

In the present study we have investigated ,using Monte Carlo simulations (MC), the adsorption of polyelectrolytes on the charged nanopatterned surfaces. Different surface's patterns were considered and we noticed that the amount of adsorption is directly dependent on the size of the domains. Also in the case of checkerboard configuration it was observed that the polyelectrolytes are aligned along the diagonal of square domains.

“…Another example where direct synthesis by controlled radical polymerization is very demanding includes preparation of polyelectrolytes. 57 The usual method of synthesis requires either protection of the ionic group or use of water as the polymerization medium rendering it incompatible with hydrophobic co-monomers. The use of BEA as a precursor enables the synthesis of random and block copolymers in a hydrophobic environment before subsequent modification to give the polyelectrolyte.…”

Poly(bromoethyl acrylate): A Reactive Precursor for the Synthesis of Functional RAFT Materials

Post-polymerization modification has become a powerful tool to create a diversity of functional materials. However, simple nucleophilic substitution reactions on halogenated monomers remains relatively unexplored. Here we report the synthesis of poly(bromoethyl acrylate) (pBEA) by reversible addition fragmentation chain transfer (RAFT) polymerization to generate a highly reactive polymer precursor for post-polymerization nucleophilic substitution. RAFT polymerization of BEA generated well-defined homopolymers and block copolymers over a range of molecular weights. The alkyl bromine containing homo-and block copolymer precursors were readily substituted by a range of nucleophiles in good to excellent conversion under mild and efficient reaction conditions without the need of additional catalysts. The broad range of nucleophilic species that are compatible with this post modification strategy enable facile synthesis of complex functionalities, from permanently charged polyanions to hydrophobic polythioethers to glycopolymers.
