Description

β-Styrenesulfonic Acid Sodium Salt is a versatile anionic monomer and intermediate widely used in polymer synthesis. Its primary value lies in introducing strongly acidic sulfonate groups into polymer chains, imparting properties like hydrophilicity, ion-exchange capacity, and dispersion stability. This makes it a critical raw material for manufacturers in the water treatment, coatings, textiles, and advanced material sectors seeking to enhance product performance.

Application

• Polymer Modification: Key monomer for synthesizing polyelectrolytes, ion-exchange resins, and superabsorbent polymers.
• Dispersants & Stabilizers: Used in the production of high-performance dispersants for pigments, dyes, and cement additives.
• Water Treatment Chemicals: Essential component in scale inhibitors and anti-fouling agents for industrial water systems.
• Textile & Leather Auxiliaries: Imparts antistatic properties and improves dye uptake in fiber treatments.
• Coatings & Adhesives: Enhances the stability and rheological properties of emulsion polymers and pressure-sensitive adhesives.
• Enhanced Oil Recovery (EOR): Used in polymers that improve the viscosity and sweep efficiency of flooding fluids.
• Pharmaceutical Intermediates: Serves as a building block for certain specialty chemicals and drug delivery systems.
