2,2'-Azobis(2-methylpropionitrile)

2,2'-Azobis(2-methylpropionitrile), commonly known as AIBN, is a highly efficient free-radical initiator widely used in polymer chemistry and organic synthesis. This white crystalline powder serves as a fundamental component in the production of various polymers, plastics, and resins through its ability to generate free radicals upon thermal decomposition.

Our AIBN product boasts exceptional purity and stability, making it ideal for both research laboratories and industrial-scale manufacturing processes requiring precise control over polymerization reactions.

Polymer Synthesis

AIBN is primarily used as a thermal initiatorfor free-radical polymerization of vinyl monomers including:

• Styrene and its derivatives
• Acrylate and methacrylate esters
• Vinyl acetate
• Acrylonitrile
• Chlorinated monomers

The controlled decomposition of AIBN allows for efficient initiation of various polymerization processes, including bulk, solution, suspension, and emulsion polymerization

Organic Synthesis

Beyond polymer chemistry, AIBN serves as a radical source in:

• Radical cyclization reactions
• Barton-type deoxygenation processes
• Hydrostannation and other addition reactions
• C-C bond formation through radical mechanisms

Industrial Applications

• Plastics manufacturing: Production of polystyrene, polyethylene, PVC, and other common plastics
• Rubber industry: Initiation of synthetic rubber polymerization
• Coating and adhesive formulations: UV-curable coatings and adhesive systems
• Specialty polymers: Synthesis of block copolymers and functionalized polymers

• Consistent decomposition ratefor predictable reaction kinetics
• Minimal oxygen inhibitioncompared to peroxide initiators
• Efficient radical generationwith nitrogen gas as the primary byproduct
• Good solubilityin most organic solvents
• Reliable performanceacross a wide temperature range

Storage Conditions:

• Store in a cool, dry, well-ventilated area
• Keep away from heat, sparks, open flames, and direct sunlight
• Maintain temperature below 30°Cfor long-term stability
• Keep container tightly closed when not in use

Safety Precautions:

• AIBN may decompose explosively if heated under confinement
• Avoid contact with strong oxidizing agents
• Use appropriate personal protective equipment (PPE) including safety glasses and lab coat
• Handle in a fume hood to avoid inhalation of dust
