Diallylamine is widely used in the synthesis of polymers and resins, particularly in the production of water-soluble polymers that are essential in various industrial applications. It serves as a key monomer in the creation of poly(diallyldimethylammonium chloride) (PDADMAC), a cationic polymer used in water treatment processes for flocculation and clarification. Additionally, it is employed in the manufacture of ion-exchange resins, which are crucial for purifying and separating substances in chemical processes. In the pharmaceutical industry, diallylamine derivatives are utilized in drug delivery systems and as intermediates for synthesizing active pharmaceutical ingredients. Its application also extends to the production of adhesives, coatings, and surfactants, where it enhances performance and stability. Furthermore, diallylamine is used in the development of corrosion inhibitors, protecting metal surfaces in industrial settings. Its versatility makes it a valuable component in various chemical and industrial processes.
