Description

Benzenesulfonic Acid, 4-Ethenyl-, Sodium Salt, Polymerwith Ethenylbenzene is a synthetic, water-soluble polyelectrolyte belonging to the class of sulfonated polystyrene polymers. This compound is valued for its strong anionic character and excellent dispersing and stabilizing properties in aqueous systems. It is primarily utilized in industries requiring high-performance rheology modifiers, scale inhibitors, and dispersants for pigments and mineral slurries.

Application

• As a dispersant and grinding aid in the production of pigments, dyes, and ceramic powders.
• As a scale inhibitor and antiscalant in industrial water treatment and reverse osmosis systems.
• As a rheology modifier and stabilizer in latex paints, coatings, and adhesive formulations.
• In enhanced oil recovery (EOR) processes as a viscosifier and mobility control agent.
• As a superplasticizer and cement dispersant in concrete and construction materials.
• For the stabilization of mineral suspensions in mining and mineral processing operations.
• In textile processing as a leveling agent and dye dispersant.
• As a template or additive in the synthesis of advanced materials and nanocomposites.

Quality Control

Our production of Sodium Polystyrene Sulfonate adheres to stringent quality management protocols. Each batch is tested to ensure consistent molecular weight distribution, sulfonation degree, and ionic content. Certificates of Analysis (COA) documenting key parameters such as assay, viscosity, pH, and residual monomers are available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent moisture absorption and caking.
