Classification of initiators
Organic peroxides
The general structural formula of organic peroxides is R-O-O-H or R-O -O-R, where R is an alkyl group, an acyl group, a carbonate group, etc.
Inorganic peroxides
Inorganic peroxides are soluble in water and are mostly used in emulsion and aqueous solution polymerization reactions. They are mainly persulfates, such as potassium persulfate, sodium persulfate, and ammonium persulfate. Among them, ammonium persulfate and potassium persulfate are the most commonly used.
Azo
Azo initiators include azobisisobutyronitrile and azobisisoheptanenitrile, which are low-activity initiators. The most commonly used one is azobisisobutyronitrile, which has an operating temperature range of 50-65°C, decomposes evenly, forms only one free radical, and has no other side reactions. It is relatively stable and can be safely stored in its pure state, but it also decomposes rapidly at 80-90°C.
Redox initiation system
Peroxide initiators and azo initiators have high decomposition temperatures (50-100°C), which limits their application in low-temperature polymerization reactions. Redox initiation systems use free radicals generated by electron transfer between oxidants and reductants to initiate polymerization reactions.

The medical field: Redox initiators composed of peroxides and amines can be widely used in the field of medical polymers. Because the redox initiator can reduce the decomposition activation energy, the polymerization can be carried out at a lower temperature, which saves energy and improves the properties of the polymer.
The chemical field: The peroxide initiator contains peroxy group (-O-O-), after heating, the -O-O- bond breaks and splits into two corresponding free radicals, thus initiating monomer polymerization, so it is suitable for aqueous solution polymerization and emulsion polymerization of polymer synthesis.
