Applications and Use Cases for Vazo™ Free Radical Initiators

Vazo™ free radical initiators can be used in a variety of applications and are available in both solvent- and water-soluble forms. They are most commonly employed as free radical polymerization initiators.

Vazo™ initiators are used to produce polymers and copolymers through bulk, solution, suspension, and, to a lesser extent, emulsion polymerizations.

Common acrylic and vinyl monomers initiated by Vazo™ include:

  • vinyl chloride
  • acrylonitrile
  • acrylic acid
  • acrylamide
  • styrene
  • ethylene
  • vinyl acetate
  • vinylidene chloride
  • methyl methacrylate
  • methyl acrylate
  • unsaturated polyesters

There are non-polymerization uses for Vazo™ initiators as well. Vazo™ initiators activate the addition of compounds such as chlorine, hydrogen sulfide, thiols, and phosphines across double bonds.

Vazo™ initiators react with unsaturated compounds in equimolar amounts to give monomers and oligomers, which contain two derivative dinitrile groups of Vazo™ initiators. These dinitriles can be further converted to amides, amines, or acids.

Vazo™ initiators activate halogenations and oxidation of:

  • Aromatic and aliphatic hydrocarbons
  • Acrylonitrile
  • Methyl methacrylate
  • Vinyl acetate

Vazo™ initiators release nitrogen gas when used, which can be used as a blowing agent.
