The formation of complex molecular architectures with low polydispersities by reversible addition fragmentation chain-transer (RAFT) polymerization renders this process of high synthetic utility. Mechanistic and kinetic studies, however, are lacking. The authors here probed the process for long-lived intermediates (see Fig.), the results of which suggested that a stable polymeric radical sink exists.
