WebOct 5, 2024 · Abstract. In the past two decades, reversible addition-fragmentation chain transfer (RAFT) process has developed into one of the most versatile methods of producing polymers with “living” chain end groups in radical polymerization. The monomers employed in RAFT polymerization are classified into two broad classes based on their reactivities.
