This chemical is primarily used in the field of polymer chemistry as a chain transfer agent. It plays a crucial role in controlling the molecular weight of polymers during the polymerization process, ensuring the production of polymers with specific properties. It is particularly effective in free radical polymerization, where it helps in regulating the growth of polymer chains, leading to more uniform and predictable polymer structures. Additionally, it finds application in the synthesis of certain types of rubber and plastics, where precise control over polymer characteristics is essential for achieving desired material properties such as elasticity, hardness, and thermal stability.
