“…A priori, the synthesis of zwitterionic polymers via post-polymerization modification shares the same advantages and inconveniences as the synthesis of other functional polymers by this approach [391]. An additional difficulty, which is particular to polyzwitterions, arises from the need to ensure the absence of excess ionic or ionizable groups after the chemical reaction(s), due to side reactions or due to incomplete conversion of reactive sites, in order to guarantee the overall zero charge condition.…”

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.

“…[338,346] 'Active ester'monomers that have been subject to RAFT polymerization are 379-386 shown inTable 25. [465] These active ester groups undergo facile reaction with, in particular, substrates with primary amine groups. Other monomers with reactive functionality that have been successfully (co)polymerized include 391 (with thiol reactive functionality) [161,162] and 392 (with protected aldehyde functionality) (Table 26).…”

This paper provides a second update to the review of reversible deactivation radical polymerization achieved with thiocarbonylthio compounds (ZC(=S)SR) by a mechanism of reversible addition-fragmentation chain transfer (RAFT) that was published in June 2005 (Aust. J. Chem. 2005, 58, 379-410). The first update was published in November 2006 (Aust. J. Chem. 2006, 59, 669-692). This review cites over 500 papers that appeared during the period mid-2006 to mid-2009 covering various aspects of RAFT polymerization ranging from reagent synthesis and properties, kinetics and mechanism of polymerization, novel polymer syntheses and a diverse range of applications. Significant developments have occurred, particularly in the areas of novel RAFT agents, techniques for end-group removal and transformation, the production of micro/nanoparticles and modified surfaces, and biopolymer conjugates both for therapeutic and diagnostic applications.

“…[56][57][58][59][60] Hence, shortly after their discoveries, these methods have been investigated for synthesizing well-defined copolymers such as statistical, gradient or alternating copolymers. [23,[61][62][63][64] In the latter case, the copolymerization of styrene with strong electron acceptors such as MAh or MIs was reported.…”

In the present Feature Article, a kinetic strategy for controlling the microstructure of synthetic polymer chains prepared via a radical chain‐growth polymerization process is presented. This approach was recently developed in our laboratory and relies on the controlled kinetic addition of ultrareactive N‐substituted maleimides during the atom transfer radical polymerization of styrene. This method is experimentally straightforward and can be applied to a broad library of functional N‐substituted maleimides. Thus, this platform allows synthesis of unprecedented polymer materials such as 1D macromolecular arrays. The basic kinetic requirements, the experimental conditions, and the synthetic scope of this approach are discussed in details herein. magnified image
