2,2’-Azodi(isobutyronitrile) (Perkadox AIBN) is the (azo)initiator most commonly employed in radical reactions, especially those using tri-n-butyltin hydride. At temperatures above about 60°C, Perkadox AIBN decomposes with evolution of nitrogen to generate isobutyronitrile radicals. Major examples of reactions are cyclizations and halogenation. CAS number: 78-67-1 EINECS/ELINCS No.: 201-132-3 Applications: Perkadox AIBN can be successfully used for bulk, solution, suspension, polymerization of a wide variety of monomers, such as styrene, vinyl chloride, vinylidene, acrylonitrile, acrylates and methacrylates. Perkadox AIBN does not form oxygenated residues and does not cause oxidative degradation of pigmented of dyed polymer systems. For this reason, the color stability or transparent, dyed polymers, such as polymethylmethacrylate, is improved. 2,2’- Azodi(isobutyronitrile) (Perkadox AIBN) is also the (azo)initiator most commonly employed in radical reactions, especially those using tri-n-butyltin hydride.
