Product Introduction:
Azobisisobutyronitrile (AIBN), additionally called “2,2′-Azobis(2-methylpropionitrile)”, is the most popular azo cost-free radical initiator.
Azobisisobutyronitrile is generally a white columnar crystal or a white powder crystal.
Insoluble in water, soluble in methanol, warm ethanol, benzene, toluene, slightly soluble in ethanol.
It should be noted that azobisisobutyronitrile exploded when dissolved in acetone and heptane.
Azobisisobutironitrile decomposes when heated to release nitrogen gas and organic cyanide containing -(CH2)2-C-CN group – which is harmful to human body.
AIBN decomposes above 60 ℃ to form isobutyronitrile group, which triggers a free radical reaction, and decomposes slowly at room temperature, and decomposes sharply at 100 ℃, which can cause explosion and fire and is flammable.

Product Usage:
- Currently the most widespread use of Azobisisobutyronitrile is as an initiator in the polymerization of plastic chlorides, vinyl acetate, polyacrylonitrile and various other monomers.
- It is also made use of as a foaming representative for rubber and also plastics, as well as the dosage is 10% to 20%.
- This item can additionally be made use of as vulcanizing agent, pesticide as well as intermediate in natural synthesis.
- It can also be made use of as a catalyst for methacrylate-embedded tissue.
- Azobisisobutyronitrile is also used as an activator for PVC plastics.
Characteristics and Production uses of Azobisisobutyronitrile:
Polyurethane
Polyurethane modification: Waterborne polyurethane modification utilizes polyurethane (PU) prepolymerized monomers, other products (modified silicones, acrylic emulsions, etc.) and Azobisisobutyronitrile initiators to react for modification.
- The polyurethane prepolymer containing NCO group is reacted with hydroxyacrylic acid, and then acrylic monomer is added for free radical polymerization to obtain polyurethane acrylate (PUA). (single component)
- The OH-containing acrylic prepolymer is reacted with the NCO group-containing polyurethane prepolymer or polyisocyanate to obtain polyurethane acrylate (PUA). (two-component)
- Add blocked polyisocyanate to OH-containing acrylate polymer. (single component)
Plexiglass/PMMA
Modified plexiglass, AIBN initiator will be used when modifying plexiglass
The use of Azobisisobutyronitrile initiators increases product clarity, and improves impact and tensile properties.
The first stage is pre-polymerized at 90-95 ℃ to a conversion rate of about 10% to obtain a viscous slurry, and then the mold is heated and polymerized in stages, generally starting from 40-45 ℃, and slowly heating up, and the later temperature reaches about 90 ℃ (needs It lasted for several days), and finally demolded into a plexiglass sheet (this process is for learning and reference, and the specific production should be based on the actual situation).
PMMA acrylic resin
The synthesis reaction of acrylic resin is a free radical reaction, which is divided into three basic processes of chain initiation, chain growth and chain termination, and is accompanied by a chain transfer process.
Note: Most of the initiators of acrylic emulsions are peroxides, such as; BPO (dibenzoyl peroxide) or APS (ammonium persulfate) /SPS (sodium persulfate), etc.
Azobisisobutyronitrile is still mainly in acrylic resins such as PMMA.
Polyether polyol/POP/white oil
Commonly used initiators in industry are azobisisobutyronitrile and benzoyl peroxide (BPO).
Synthetic Plastic – Vinyl / VER
Vinyl resin ester (VER)
A part of the synthetic resin (plastic) formed by the polymerization of a vinyl monomer (CH2=CH).
Including polyvinyl chloride, polyvinylidene chloride, polyvinyl acetate and its derivatives (polyvinyl alcohol, polyvinyl acetal), polyvinyl ether, polyvinyl carboxy}`, poly (N-vinyl pyrrolidone) )Wait.
Synthetic Plastic – ABS
ABS production mainly includes emulsion grafting, emulsion grafting blending method and continuous bulk method.
The emulsion grafting method has now been replaced by the emulsion grafting blending method.
The emulsion graft blending method is to carry out emulsion graft copolymerization of part of styrene (PS) monomer and acrylonitrile with polybutadiene latex, and another part of styrene monomer and acrylonitrile monomer to copolymerize to form SAN, By blending the two in different proportions, various grades of ABS resin can be obtained. The continuous bulk method refers to the use of 3-5 continuous reactors in series.
ABS modified
Study on the grafting of maleic anhydride (MAH) on ABS by solution grafting method, such as using dicumyl peroxide (DCP) and azobisisobutyronitrile as initiators in suitable acetone or tetrahydrofuran. -Methacrylic acid graft copolymerization to ABS.
