Used primarily as a free radical initiator in polymerization reactions. It decomposes upon heating to generate nitrogen gas and reactive radicals, which initiate the formation of polymers from monomers like styrene, acrylonitrile, and vinyl chloride. Commonly employed in the production of plastics, synthetic rubbers, and adhesives. Its oil-soluble nature makes it suitable for use in solution, bulk, and suspension polymerization processes. Also utilized in the synthesis of specialty polymers where precise control over molecular weight and reaction rate is required. Due to its thermal instability, it is effective at moderate temperatures, allowing for safer and more controlled industrial processing.
