A Micro Review of Reversible Addition/Fragmentation Chain Transfer (RAFT) Polymerization

We presents an article about a micro review of reversible addition/fragmentation chain transfer (RAFT) polymerization. RAFT (Reversible Addition/Fragmentation Chain Transfer) polymerization is a reversible deactivation radical polymerization (RDRP) and one of the more versatile methods for providing living characteristics to radical polymerization.
