Product Overview

Vazo® free radical sources from DuPont provide efficient initiation of many chemical reactions, including:

  • acrylic and vinyl polymerizations
  • halogenations (brominations)
  • oxidations and related chain reactions
  • additions of small molecules across olefinic double bonds
  • cross-linking

Product Description

The DuPont™ Vazo® free radical sources are substituted azonitrile compounds that thermally decompose to generate two free radicals per molecule. (Nitrogen gas is also generated.) The rate of decomposition is first-order and is unaffected by contaminants such as metal ions.

Vazo® free radical sources are used to initiate bulk, solution, and suspension polymerizations. Vazo® products can be used alone, or in combination with other free radical initiators.
