usage
AIBN is a particularly excellent free radical initiator. When heated to about 70 ° C, it decomposes and releases nitrogen gas, generating free radicals (CH3)2CCN, Free radicals are more stable due to the influence of cyanide groups. It can react with another organic substrate, annihilate itself, and regenerate into a new free radical, thereby triggering a chain reaction of free radicals (see free radical reaction), When heating AIBN to 100-107 ° C, it melts and undergoes rapid decomposition,
Used as a polymerization initiator for monomers such as polyvinyl chloride, polyvinyl alcohol, polystyrene, and polyacrylonitrile. Used as an intermediate in organic synthesis. Used as an initiator for high molecular polymers
Used as an initiator for polymerization or copolymerization of vinyl acetate and acrylic esters.
Used as a foaming agent.
Application: A catalyst for embedding tissues in methyl methacrylate. The initiator of polymer. Rubber, plastic, foaming agent. Polychloroethylene plastic activator
