| dc.description | The reversible addition–fragmentation chain transfer (RAFT) process is the most recent of the living/controlled free radical methodologies that have revolutionized the field of free radical polymerization. It was invented in 1998 by the Common- wealth Scientific and Industrial Research Organization (CSIRO) in Melbourne, Australia, by a team of several researchers [1]. Almost simultaneously, a group of researchers in France patented a process they termed macromolecular design via the interchange of xanthates (MADIX) [2], which employed xanthates as controlling agents but proceeds by an identical mechanism as the CSIRO-reported RAFT pro- cess. Both processes are based on earlier developed chemistries, such as the small radicalreactionspioneeredbyZardandcoworkers[3].Equally,polymerizationsem- ploying reversible addition–fragmentation chain transfer principles, which showed some of the characteristics of living polymerization, were first reported in 1995 by the CSIRO group [4]. The RAFT process employs a fundamentally different con- ceptual approach compared to nitroxide-mediated polymerization (NMP) and atom transfer radical polymerization (ATRP) in that it relies on a degenerative chain transfer process and does not make use of a persistent radical effect to establish control. Such an approach has the important consequence that the RAFT process features quasi-identical rates of polymerization – apart from deviations caused by the chain length dependence of some rate coefficients – as the respective conven- tional free radical polymerization processes. Among the other unique features of the RAFT process is its high tolerance to functional monomers – such as vinyl acetate and acrylic acid – which can be polymerized with living characteristics with ease. The RAFT process is an equally powerful tool for the construction of com- plex macromolecular architectures via variable approaches – i.e. the so-called Z- and R-group designs – that allow for almost limitless possibilities in the synthetic protocols in terms of the low molecular weight scaffolds that support the complex structure. | en |
