Abstract:Copolymers of poly(ethylene glycol) methyl ether methacrylate (PEGMA) and one of two dioxolane-containing monomers, (2,2-dimethyl-1,3-dioxolane)methyl acrylate (DDMA) and (2,2-dimethyl-1,3-dioxolane)methyl acrylamide (DDMAA), were successfully synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization. RAFT copolymerization was performed in dimethylformamide (DMF) at 70°C for 24 h using 4,4′-azobis(4-cyanovaleric acid) as initiator and N-(sodium ethane sulfonic acid)-2-((thiobenzyl)… Show more

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.

This article reviews the mechanistic and practical aspects of free radical polymerization with reversible addition–fragmentation chain transfer—the reversible addition–fragmentation chain transfer (RAFT) process. RAFT is conducted by the addition of a thiocarbonylthio compound (ZC(S)SR) to a conventional radical polymerization. Suitable RAFT agents include dithioesters, trithiocarbonates, dithiocarbamates, and xanthates. These thiocarbonylthio compounds confer living characteristics to the radical polymerization by a mechanism of reversible addition–fragmentation chain transfer and provide exceptional control over molecular weight, molecular weight distribution, composition, and architecture of the resulting polymers. The process can be applied to most monomers polymerizable by radical polymerization and offers a convenient route to well‐defined homo‐, gradient, diblock, triblock, and star polymers as well as more complex architectures including microgels and polymer brushes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
