AIBN: A Deep Dive into the Polymerization Catalyst

AIBN, or azobisisobutyronitrile, serves one key role as radical polymerization reactions. The substance operates the photo initiator, undergoing breakdown at application by UV and radiation, producing reactive radicals. These species then start chain-growth of monomers, leading in plastic growth. The cleavage kinetics are highly dependent on temperature, enabling this the useful tool for controlling the process.
