Sodium β-Styrenesulfonate is widely used as a monomer in the production of polymers and copolymers, particularly in the creation of ion-exchange resins essential for water treatment processes, including impurity removal and water softening. Its sulfonate groups enhance adhesion and durability in the manufacture of specialty coatings and adhesives. In biomaterials, it modifies surfaces to improve biocompatibility, making it valuable for medical devices and drug delivery systems. It also serves as a key component in the synthesis of hydrogels applied in wound dressings and contact lenses. Furthermore, it imparts hydrophilicity, ionic properties, thermal stability, and corrosion resistance to materials. In anionic polymers, it facilitates oil-water separation. Additional applications include the paper industry for enhancing strength and durability, and the textile industry for improving dyeing and water absorption.
