Applications

Ammonium peroxydisulfate is widely utilized as an oxidizing agent and radical initiators in the polymerization of certain alkenes. It is actively involved in in the synthesis of commercially important polymers like styrene-butadiene rubber and polytetrafluoroethylene. It combines with tetramethylethylenediamine to catalyze the polymerization of acrylamide. Due to its oxidizing properties, it can be employed to etch copper on printed circuit boards which is an alternative to ferric chloride solution. Also, it acts as oxidants in organic synthesis.

Notes

Aqueous solution decomposes slowly at room temperature.Moisture sensitive. Incompatible with strong reducing agents, organic materials and powdered metals.
