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.

“…BA polymerizes over short periods of time, due to its high kp-value [47], and was extensively investigated in Z-RAFT star polymerization in our group [21,23,24,[48][49][50]. Poly-N-isopropylacrylamide (PNIPAam) on the other hand, is a hydrophilic polymer with switchable properties: Below a temperature of 32 °C, the polymer is water-soluble; rising the temperature above this critical barrier-the so-called lower critical solution temperature (LCST)-the coil collapses [51] and is no longer soluble in water.…”

Tailoring Confinement: Nano-Carrier Synthesis via Z-RAFT Star Polymerization

Abstract:A new pathway to nano-sized hollow-sphere particles from six-arm star polymers with an amphiphilic core-corona structure, synthesized in a four-step-procedure by means of reversible addition-fragmentation chain transfer (RAFT) polymerization is presented, in order to achieve more stable and versatile nano-container systems, which could be applied in the fields of drug delivery or catalyst storage. Star-shaped amphiphilic, diblock copolymers serve as globular platforms for synthesizing uniform hollow structures. By the introduction of monomer units carrying UV-cross-linkable dimethyl maleimido functionalities into the outer sphere of these star polymers, the carrier's shell could be stabilized under UV-irradiation. After removal of the RAFT-core-constituting the central hub of the star polymer-by aminolysis, the carrier is ready for loading.

In Situ Reversible Addition–Fragmentation Chain Transfer Polymerization of Styrene in the Presence of MCM‐41 Nanoparticles: Comparing “Grafting from” and “Grafting through” Approaches

et al. 2013

ABSTRACT:The preparation of polystyrene/MCM-41 nanocomposites was carried out by "grafting from" and "grafting through" approaches and in the presence of unmodified MCM-41, using reversible addition-fragmentation chain transfer (RAFT) polymerization. The MCM-41 was modified by attaching S-dodecyl-S -(α,α -dimethyl-α -acetic acid)trithiocarbonate (DDMAT) as the RAFT agent and methacrylate group using 3-methacryloxypropyldimethylchlorosilane. The kinetics of styrene RAFT polymerization by different approaches was compared with the model polymerization mediated by free DDMAT. The quantity of the grafted chain grown from the surface and inside of the pores of MCM-41 and free polymer chains in bulk was determined by thermogravimetric analysis. The molecular weight of the produced polymer chains increased linearly with the monomer conversion for three methods. The gel permeation chromatography showed that the molecular weight of grafted and free polymer chains in the "grafting from" approach is higher than other methods, and molecular weight distributions were relatively narrower whereas the rate of polymerization for "grafting from" was higher.
