Application

2,2′-Azobis(2-methylpropionitrile) can be used as an initiator in the preparation of:
  • Polystyrene by soap-free emulsion polymerization.
  • Molecularly imprinted polymer(MIP) using 1-vinyl imidazole. MIP can be used to quantify acid violet 19 dye in river water samples.[1]

A molecularly imprinted polymer (MIP) was developed for the determination of acid violet 19 (AV19) dye. The MIP was synthesized by polymerization using 1-vinyl imidazole (functional monomer) and 2,2'-azobis(2-methylpropionitrile) as the radical initiator. The functional monomer was previously selected by
