  • Applications

    2,2'-Azobis(2,4-dimethylvaleronitrile) (CAS 4419-11-8) is a thermal azo radical initiator used to trigger free-radical polymerization in a range of resins and monomers. It is commonly employed as a heat-activated initiator for polymerizations of vinyl monomers such as styrene, acrylates, and acrylonitrile at controlled temperatures. Real-world applications include: polymers/plastics production (initiation of bulk/solution polymerizations to form plastics and copolymers); coatings and inks (heat-cured coatings and resin-based inks); adhesives and sealants (thermally cured adhesive formulations); rubber and elastomer manufacturing (emulsion or solution polymerizations to produce synthetic rubber); and specialty polymers/composites (synthesis of high-performance polymers and composite materials).
