A Versatile Initiator for Controlled Polymerization
Azobisisobutyronitrile (AIBN) is a critical organic compound widely employed in polymer chemistry as a photoinitiator or thermal initiator. It plays a pivotal role in crosslinking processes, enabling chemists to precisely control polymerization rates, molecular weights, and polydispersity. Its convenient decomposition properties make it an ideal choice for initiating a broad spectrum of monomers, ensuring efficient and controlled production of high-quality polymers.
