Product Overview
Azobisisobutyronitrile (AIBN) is a typical azo-type free radical initiator. When heated, it decomposes to generate free radicals and releases nitrogen gas, thereby initiating free radical polymerization reactions. Its decomposition behavior is stable and easy to control, making it widely used in the polymer, resin, and fine chemical industries. Typically heated at 60–80°C, AIBN undergoes homolytic cleavage of the azo bond with smooth and predictable reaction progression, making it suitable for most industrial polymerization systems.
Due to its symmetrical molecular structure and single radical generation pathway, AIBN effectively reduces side reactions and enables precise control of molecular weight distribution. In industrial production, it is commonly used in acrylic resins, styrene polymerization, acrylonitrile production, synthetic rubber, and various functional polymer materials.

.
Product Advantages
Compared with peroxide initiators, AIBN offers several practical advantages in industrial applications:
- Milder and more controllable reaction process, improving safety
- More uniform radical generation
- Better molecular weight control
- Clean system with nitrogen as the main by-product
- Suitable for solution, bulk, and emulsion polymerization
Buyer Benefits
Using high-purity AIBN helps customers achieve improved production performance:
- Higher polymerization efficiency and shorter reaction cycles
- Improved molecular weight distribution consistency
- Reduced side reactions and gel formation
- Better final product performance (clarity, strength, stability)
- Lower process adjustment and energy costs
Evidence or Case Studies
Industrial applications in acrylic and styrene systems show that AIBN usage can lead to:
- Improved process stability
- Reduced batch-to-batch variation
- Narrower molecular weight distribution
- Lower impurity and by-product formation
Since nitrogen is the main decomposition product, residue levels are low, making it suitable for high-purity resins and functional materials.
