설명
A polymerization accelerant for PAGE gels. Potassium peroxydisulfate is used as an oxidizing agent in organic synthesis. It is involved in Elbs persulfate oxidation of phenols and the Boyland-Sims oxidation of anilines. Upon solution, it gives radicals and is used to initiate polymerization reactions to prepare styrene-butadiene rubber and polytetrafluoroethylene. It is used as bleaching agent in various hair bleaches, ion exchange agents, plating agents and surface treating agents.
