Sodium 4-styrenesulfonate
Sodium 4-styrenesulfonate (CAS: 2695-37-6) is a reactive water-soluble monomer featuring a vinyl group for polymerization and a sulfonate group that imparts strong anionic character to derived polymers. This white crystalline solid readily undergoes free-radical polymerization alone or with comonomers such as acrylamide, acrylic acid, and styrene, producing polymers with excellent water solubility, dispersing power, and electrolyte tolerance. The resulting polyelectrolytes serve as dispersants in water treatment, scale inhibitors, pigment dispersing agents, and flocculants in mineral processing. In personal care, sulfonated polymers provide conditioning and fixative properties in hair styling products. The textile industry uses these polymers as dyeing auxiliaries and anti-redeposition agents in detergent formulations. With its dual reactivity and performance attributes, sodium 4-styrenesulfonate is a valuable monomer for functional polymer design across water treatment, coatings, and consumer product industries.
– Functional Polymer Synthesis: Used as a comonomer to introduce sulfonate functionality into water-soluble polymers for enhanced dispersing and anti-scaling performance.
– Water Treatment Chemicals: Serves as a building block for dispersants and scale inhibitors in cooling towers, boilers, and reverse osmosis systems.
– Detergent and Textile Additives: Applied in anti-redeposition agents and dye-leveling auxiliaries improving wash performance and color uniformity.
– Personal Care Polymers: Incorporated into hair fixatives and conditioners as anionic comonomers providing hold and substantivity.
