The penultimate unit effects (PUEs) on the propagation, termination, and reversible addition‐fragmentation chain transfer (RAFT) processes in free radical copolymerization are discussed on the basis of recent publications. The propriety of the implicit and explicit PUE models in propagation and chain transfer processes is commented. The penultimate termination model with the geometric‐mean approximation and the related rate equation are highlighted.
