Vazo™ Free Radical Initiators

Substituted Azonitrile Compounds

Vazo™ free radical initiators from The Chemours Company provide efficient initiation of many chemical reactions, including:

  • Acrylic and vinyl polymerizations
  • Halogenations
  • Oxidations
  • Cross-linking
  • Additions of small molecules across olefinic double bonds

Vazo™ initiators are substituted azonitrile compounds that thermally decompose to generate two free radicals per molecule along with a mole of nitrogen gas. The rate of decomposition is first-order and is unaffected by contaminants such as metal ions, or by solvent choice.

Vazo™ initiators are used to initiate bulk, solution, suspension, and emulsion polymerizations. Chemours offers Vazo™ initiators in a variety of grades to suit specific use cases. View the full product line and applications below.
