VAZO 64 | Azobisisobutyronitrile

Vazo 64, also known as AIBN (Azobisisobutyronitrile), is a free radical source (FRS) typically used as a polymerization initiator. Vazo 64 is one of the most widely used initiators, which thermally decomposes to generate free radicals and nitrogen gas. More cost-effective than organic peroxides of comparable activity. Its low molecular weight allows it to be one of the most cost effective options, with a higher mole per pound than other initiators. Vazo 64 is mainly used to start acrylic polymerization reactions in industrial settings.  Benefits include:

  • Very Cost Effective
  • Does not compete in costly sides reactions
  • Head-to-Tail polymerization; Low polydispersity
  • Unaffected by heavy metals, contamination, additives etc
  • Can polymerize oxidation susceptible compound
