偶氮二异丁腈
12 wt. % in acetone
别名:
2,2′-偶氮(2-甲基丙腈) 溶液, α,α,′-偶氮异丁腈 溶液, AIBN 溶液
一般描述
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.
应用
- 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).
特点和优势
Decomposes unimolecularly at good rates without much variation from one solvent to another.

Polystyrene (PS) microspheres were synthesized via dispersion polymerization in alcoholic media. A cationic polyelectrolyte, polyethyleneimine (PEI) was successfully used as a steric stabilizer. The concentration of initiator, monomer, and the solubility parameter of medium showed typical phenomena observed in dispersion
