In the rapidly evolving field of advanced materials, Azobisisobutyronitrile (AIBN), as a key free radical initiator, is driving innovation in polymer synthesis technology. This highly efficient and stable chemical raw material has become the core catalyst for numerous high-end polymer production processes.
Core Advantages
-
Efficient Initiation: Controllable decomposition temperature of 60–80°C
-
Mild Reaction Conditions: Suitable for various polymerization systems
-
Excellent Purity: Industrial-grade purity of ≥99%
-
Broad Applications: Covering plastics, rubber, coatings, and many other fields
Mechanism of Action
Under heating conditions, the azo bond (-N=N-) in the AIBN molecule undergoes homolytic cleavage, generating highly active isobutyronitrile free radicals. These radicals efficiently initiate the chain polymerization of olefin monomers, constructing the polymer backbone.
Innovative Application Scenarios
High-End Plastic Synthesis
-
Preparation of optical-grade PMMA (acrylic glass)
-
Production of high-impact ABS engineering plastics
-
Synthesis of medical-grade polymer materials
