Used as a chain transfer agent in reversible addition-fragmentation chain transfer (RAFT) polymerization, enabling precise control over molecular weight and polydispersity of synthesized polymers. It is particularly effective in the polymerization of methacrylic and acrylate monomers, facilitating the production of block copolymers and complex macromolecular architectures. Its selective reactivity makes it valuable in designing functional polymers for coatings, adhesives, and specialty materials.
