“…Our initial communication on this form of RAFT polymerization [13] focussed on the utility of dithiobenzoate (Z = Ph) and other dithioesters. However, our patents [14,38,45] and subsequent papers demonstrate that a wide range of thiocarbonylthio compounds can be used. These include certain trithiocarbonates, xanthates, dithiocarbamates, and other compounds.…”

“…Electron-withdrawing substituents on Z can enhance the activity of RAFT agents to modify the above order. [38,[46][47][48][49] Thus, xanthate and dithiocarbamate RAFT agents where the oxygen or nitrogen lone pair is less available for delocalization with the C S by virtue of being part of an aromatic ring or by possessing an adjacent electron-withdrawing substituent are substantially more effective. For examples see Table 6 (xanthates) or Table 4 (dithiocarbamates).…”

This paper presents a review of living radical polymerization achieved with thiocarbonylthio compounds [ZC( S)SR] by a mechanism of reversible addition-fragmentation chain transfer (RAFT). Since we first introduced the technique in 1998, the number of papers and patents on the RAFT process has increased exponentially as the technique has proved to be one of the most versatile for the provision of polymers of well defined architecture. The factors influencing the effectiveness of RAFT agents and outcome of RAFT polymerization are detailed. With this insight, guidelines are presented on how to conduct RAFT and choose RAFT agents to achieve particular structures. A survey is provided of the current scope and applications of the RAFT process in the synthesis of well defined homo-, gradient, diblock, triblock, and star polymers, as well as more complex architectures including microgels and polymer brushes.

This article provides an overview of the preparation, properties, use, and characterization of synthetic copolymers. The range of different copolymer structures that can be synthesized using current methods is detailed and the current IUPAC‐recommended nomenclature for naming these structures is explained. Techniques for the production of copolymers are discussed, with an emphasis on the types of copolymers and copolymer structures attainable through each polymerization technique. Industrially important random, alternating, block, graft, star, and hyperbranched copolymers are described in terms of the processes used to produce them and the properties achieved. Their main uses and major producers are also detailed.
