This perspective provides a comprehensive overview of the features and limitations of reversible addition–fragmentation chain transfer (RAFT) polymerization, a versatile and powerful technique for synthesizing complex polymeric architectures. RAFT, a type of reversible deactivation radical polymerization (RDRP), has gained widespread recognition over the past 20 years due to its ability to produce polymeric structures with predictable molecular weight, low molar mass dispersity, and high end-group fidelity. The mechanism of RAFT involves an equilibrium between active and dormant chains, achieved through degenerative transfer, where the number of radicals is controlled by the initiator. This process allows for the synthesis of various monomers, including vinyl, acrylate, and acrylamide derivatives, with high control over molecular weights and dispersity. The perspective covers the selection of RAFT agents, end-group modification, and the process of polymerization, including homogeneous, heterogeneous, and flow polymerization methods. It also highlights the industrial applications of RAFT, such as in microelectronics, plastic solar cells, and cosmetics, and discusses the commercial availability of RAFT agents. Overall, RAFT polymerization offers a robust and flexible tool for creating a wide range of polymeric materials.This perspective provides a comprehensive overview of the features and limitations of reversible addition–fragmentation chain transfer (RAFT) polymerization, a versatile and powerful technique for synthesizing complex polymeric architectures.
