Widely used as a free radical initiator in polymerization processes, especially in the production of acrylic and styrenic polymers. It is effective in emulsion, suspension, and bulk polymerizations due to its ability to decompose into radicals at moderate temperatures. Commonly applied in the synthesis of plastics, adhesives, coatings, and synthetic rubbers. Its solution form improves handling safety and dosing accuracy compared to the solid form, reducing the risk of dust explosion and thermal runaway. Also used in specialty applications such as crosslinking agents and in the generation of reactive species for chemical research.
