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.

“…Playing on the free volume of the polymer chain and the strength of polymer-polymer interactions can also influence the behavior of poly(vinyl ester)s in solution. A recent example is the solubility of PVAc in supercritical carbon dioxide (scCO 2 ) that can be enhanced via the copolymerization of VAc with hindered [3][4][5][6] or fluorinated vinyl esters [7][8][9]. The kinetics of hydrolysis of the ester group can also be strongly affected by steric hindrance and polar effects.…”

“…The advent of reversible-deactivation radical polymerization [28] has led to an increased interest in poly(vinyl ester)s by enabling the control of the main characteristics of polymer chains such as molar mass and molar mass distribution, end-groups and architecture. Numerous recent studies have focused on complex polymer architectures with original solid state morphologies [30][31][32][33], PVA-based surfactants [34,35] or poly(vinyl ester)s with enhanced solubility in scCO 2 [3][4][5][6][7][8]. To date, iodine-transfer polymerization (ITP) [36], organoheteroatom-mediated polymerization (OMRP) [28,37], cobalt-mediated polymerization (CoMRP) [38] and reversible addition-fragmentation chain transfer (RAFT) polymerization [39] have been proven efficient in the radical polymerization of vinyl esters.…”

RAFT Polymerization of Vinyl Esters: Synthesis and Applications

et al. 2014

View full text Add to dashboard Cite

This article is the first comprehensive review on the study and use of vinyl ester monomers in reversible addition fragmentation chain transfer (RAFT) polymerization. It covers all the synthetic aspects associated with the definition of precision polymers comprising poly(vinyl ester) building blocks, such as the choice of RAFT agent and reaction conditions in order to progress from simple to complex macromolecular architectures. Although vinyl acetate was by far the most studied monomer of the range, many vinyl esters have been considered in order to tune various polymer properties, in particular, solubility in supercritical carbon dioxide (scCO 2 ). A special emphasis is given to novel poly(vinyl alkylate)s with enhanced solubilities in scCO 2 , with applications as reactive stabilizers for dispersion polymerization and macromolecular surfactants for CO 2 media. Other miscellaneous uses of poly(vinyl ester)s synthesized by RAFT, for instance as a means to produce poly(vinyl alcohol) with controlled characteristics for use in the biomedical area, are also covered.

Polymerizations in Supercritical Carbon Dioxide

Encyclopedia of Polymer Science and Technology

The science and engineering of polymerizations carried out in supercritical carbon dioxide (scCO2) have been studied abundantly in the literature in the last three decades. There are several very good and recent reviews on the topic available in the literature. This article is based on a related contribution by Jones and DeSimone published in this encyclopedia, which emphasized the polymer chemistry background of this topic. The material is updated and enriched from a polymer reaction engineering perspective. The commercial feasibility of polymerization processes carried out in scCO2was proven early by DuPont, which built a commercial plant for production of fluoropolymers in Fayetteville, North Carolina, USA. Unfortunately, the commercial development of new polymerization processes in scCO2slowed down due to environmental and pollution issues associated to some chemicals used in the production of fluoropolymers. However, many new materials and polymerization variants in scCO2keep on resurfacing. The science and technology of polymerization processes carried out in scCO2and novel materials produced therein has reached a relatively mature state and the development of commercial processes for production of some of these materials is certainly feasible in the near future.
