Reversible addition fragmentation chain transfer (RAFT) mediated polymerisation is one of a number of living radical polymerisation processes that were developed over the last decade. The RAFT process is facilitating the synthesis of controlled macromolecular architectures radical polymerisation in homogeneous and heterogeneous media. Here we discuss the progress in the use of the RAFT process, the past, the state of the art and potential directions for the future with specific emphasis on heterogeneous reactions.
