Vazo™ 67
Vazo™ 67 is an oil-soluble 2,2’-azobis(methylbutyronitrile) (AMBN) compound used to safely and efficiently initiate free radical polymerizations.
Vazo™ 67, chemically known as 2,2’-azobis(methylbutyronitrile) (AMBN), is a substituted azonitrile-based compound that serves as an excellent source of free radicals needed to initiate free radical polymerization. It decomposes when exposed to heat to form nitrogen gas and free radical intermediates.
Vazo™ 67 provides performance advantages and convenience compared to other initiators as it will not undergo redox reactions, can be blended with other initiator systems without radical-induced decomposition, and functions as intended, regardless of pH. The free radicals generated by Vazo™ 67 will also not abstract hydrogen from growing polymer chains, allowing more control over polymer structure and preventing chain defects, branching, and cross-linking during polymerization. This makes it a higher-performing initiator in a variety of applications, including the manufacture of specialty resins, chemicals, and intermediates.
As an AMBN initiator, Vazo™ 67 performs like AIBN initiators but yields safer decomposition products. Like other Vazo™ initiators, the number designated in the grade name indicates the 10-hour half-life temperature. Thus, Vazo™ 67 has a 10-hour half-life temperature at 67°C. It must be stored below 24°C, away from light and ignition sources, to ensure product quality and safety. For more information on the benefits and use cases for Vazo™, review the article near the bottom of this page.
