Sodium p-Styrenesulfonate Hydrate is widely used in the production of polymers and copolymers, particularly in water-soluble resins and ion-exchange materials. It serves as a key component in the manufacture of superabsorbent polymers, which are essential in hygiene products like diapers and sanitary napkins. Additionally, it is employed in the development of coatings and adhesives, enhancing their stability and performance. In the field of water treatment, it acts as a dispersant and anti-scaling agent, preventing the buildup of mineral deposits. Its applications also extend to the biomedical sector, where it is used in drug delivery systems and hydrogels for controlled release of active ingredients.
