Vazo™ Free Radical Initiators


Vazo™ Free Radical Initiators are substituted azonitrile compounds that are used as initiators for bulk, solution, suspension, and emulsion polymerizations.  These azo compounds decompose when exposed to heat or light to form one mole of nitrogen gas and two free radical intermediates per molecule of Vazo™.  Vazo™ Free Radicals are used to initiate halogenation, oxidation, and acrylic & vinylic polymerizations.  Vazo™ Free Radical Initiators are more stable than organic peroxides and allow for much more control over final polymer structure making them more useful for specialty polymer development.

Vazo™ Free Radical Initiators are commercially available in oil soluble and water soluble grades and are classified by thermal decomposition temperature.  

Problems Solved
