This chemical is primarily used as a radical initiator in polymerization reactions, particularly in the production of polymers and copolymers. It is effective in initiating the polymerization of vinyl monomers, such as acrylates and methacrylates, due to its ability to decompose and generate free radicals at moderate temperatures. It is also employed in the synthesis of functionalized polymers, where its carboxyl groups can be utilized for further chemical modifications. Additionally, it finds application in the preparation of microgels, nanoparticles, and other advanced materials, often in aqueous or organic solvent systems. Its water-soluble nature makes it suitable for use in emulsion and suspension polymerization processes.
