Perkadox AIBN
2,2'-Azobis(isobutyronitrile)
CAS Number: 78-67-1
Physical Form: Solid
We supply azo initiators, such as Perkadox® AIBN (azodibutyronitrile) and Perkadox® AMBN (2-methylbutyronitrile), for the bulk, solution, suspension, and emulsion polymerization of various monomers (e.g., 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; for example, they do not form oxidative byproducts and result in minimal yellowing. Azo initiators generate only C-centered radicals, which are low in energy, highly selective, and have low branching. This results in low polydispersity index (PDI) values and molecular weights. Perkadox® AIBN does not form oxidative residues nor does it cause oxidative degradation of pigments in colored polymer systems. For this reason, color stability is improved in transparent colored polymers, such as polymethyl methacrylate (PMMA). AIBN and other azo initiators provide excellent color stability in transparent, colored polymers (such as PMMA). They do not form oxidative residues nor cause oxidative degradation in coloring or dyeing systems. Compared to organic peroxides, azo initiators prevent excessive grafting, making them particularly suitable for the manufacture of acrylic cast and molded sheets, as well as adhesives, acrylic fibers, superabsorbent polymers, detergents, and flocculants. Our most commonly used initiator is AIBN, but our AMBN offers better solubility than AIBN. Perkadox® AIBN can also be used in pharmaceuticals and fine organic synthesis. Our Trigonox 421 offers similar technical performance and serves as a sustainable alternative to AIBN. Another advantage of Trigonox 421 is that all decomposition products are non-toxic, in contrast to AIBN, which forms toxic TMSN.
