This chemical is primarily used as a chain transfer agent in controlled radical polymerization processes, such as reversible addition-fragmentation chain transfer (RAFT) polymerization. It helps regulate the molecular weight and distribution of polymers, enabling the synthesis of well-defined polymers with specific properties. This makes it valuable in producing advanced materials like block copolymers, functional polymers, and polymers with narrow molecular weight distributions. Its application is particularly significant in industries such as coatings, adhesives, and specialty polymers, where precise control over polymer architecture is essential for achieving desired performance characteristics.
