General description
Azobisisobutyronitrile (AIBN) is an azo-compound and is widely used as a free radical initiator. This compound has labile carbon-nitrogen covalent bond which undergoes homolytic scission under thermal, chemical or photochemical conditions producing free radicals. They are useful in many reactions like halogenation, polymerisation of vinyl monomers, grafting reactions, curing of rubbers and unsaturated polymers and cross-linking of polyolefins.
Application
- Used as an initiator in the synthesis of highly cross-linked Poly(divinylbenzene) (PDVB) polymers.
- Used as an initiator in the polymerization process of 2-hydroxyethyl methacrylate (HEMA).
Features and Benefits
Decomposes unimolecularly at good rates without much variation from one solvent to another.

The magnetic Ni nanoparticles functionalized water-soluble graphene sheets nanocomposites (Ni@GSs-C(CH(3))(2)COONa) were fabricated via a facile and mild strategy. We designed a simple and efficient approach (the addition of cyano radicals) to improve the water solubility of nanocomposites. The Ni@GSs-C(CH(3))(2)COONa nanocomposites
