Used as a radical initiator in polymer chemistry, particularly effective in emulsion and suspension polymerizations where controlled initiation at moderate temperatures is required. Its low solubility in water makes it suitable for use in two-phase systems, ensuring initiation primarily occurs in the monomer phase. Commonly applied in the production of styrenic polymers, acrylics, and synthetic rubbers. Also utilized in graft copolymerization processes due to its ability to generate radicals efficiently without requiring metal catalysts. Stable under storage conditions, it offers safe handling and consistent performance in industrial-scale polymer manufacturing.
