1, Brief introduction for 2,2'-AZOBISISOBUTYRONITRILE :
||White crystalline or white powder crystals, flammable. The melting point is 105 degrees (decomposition). Nitrogen and organic cyanide are released by thermal decomposition.
||It is insoluble in water, soluble in methanol, ethanol, acetone, ethyl ether, petroleum ether and aniline.
It can be used as initiator of polymer such as polyvinyl chloride, polyvinyl acetate, polyacrylonitrile, organic glass and ion exchange resin.
Plastics and rubber foaming agents.
