Effects of Diffusion‐Controlled Radical Reactions on RAFT Polymerization

Abstract The ‘livingness’ of a controlled radical polymerization process such as reversible addition–fragmentation transfer polymerization (RAFT) depends on the rapid deactivation of propagating radicals (the radical addition reaction in RAFT) that suppresses radical termination reactions. However, at high monomer conversions when the polymerization system becomes viscous, polymer chains may experience diffusion limitations and the radical …
