Nouryon Perkadox AIBN-PD 2,2′-Azobis(isobutyronitrile) 78-67-1
We offer azo initiators such as Perkadox® AIBN (azobisisobutyronitrile) and Perkadox® AMBN (2-methylbutyronitrile) for use with a variety of monomers such as styrene, vinyl chloride, vinylidene chloride, acrylonitrile, acrylates and methacrylates. Our most commonly used initiator is AIBN, but our AMBN offers better solubility than AIBN. Advantages of AIBN initiators: Azo initiators offer many advantages over standard organic peroxides, such as they do not form oxidation by-products and offer low yellow discoloration. Azo initiators produce only C-centered radicals, which are low energy, highly selective and low branched. This provides low polydispersity index (PDI) values and molecular weights. AIBN and other azo initiators provide excellent color stability in transparent colored polymers such as PMMA. They do not form oxidative residues or cause oxidative degradation of coloring or dyeing systems. In contrast to organic peroxides, azo initiators avoid over-grafting, making them particularly suitable for the manufacture of acrylic cast and molded sheets, as well as adhesives, acrylic fibers, superabsorbents, detergents and flocculants. Perkadox® AIBN is also used in pharmaceuticals and fine organic synthesis. Our Trigonox 421 offers similar technical properties and is a sustainable alternative to AIBN. Another advantage of Trigonox 421 is that all decomposition products produced are non-toxic, in contrast to AIBN, which forms toxic TMSN.
