redoxinitiated
Redox-initiated refers to the initiation of chemical reactions, especially radical polymerization, through redox reactions between an oxidizing and a reducing component that generate radicals capable of starting chain growth. These systems enable polymerization at ambient temperatures and are used when heat-sensitive substrates must be preserved.
Common redox-initiated systems include ammonium persulfate with TEMED in aqueous media, where persulfate oxidizes TEMED to
Mechanistically, the oxidant accepts electrons from the reductant, forming radical species that attack monomer double bonds
Applications include gel formation for electrophoresis, dental resins, coatings, and adhesives where room-temperature curing is advantageous.
