Description

Ammonium Vinylbenzenesulphonate is a reactive anionic monomer, a key intermediate in the synthesis of specialized polymers. Its primary value lies in introducing permanent sulfonate functionality and polymerizable vinyl groups into macromolecular chains, significantly enhancing hydrophilicity, ionic conductivity, and dye receptivity. This compound is essential for manufacturers in the water treatment, specialty coatings, and advanced material sectors seeking to engineer polymers with specific surface-active or ion-exchange properties. Its utility is further amplified in applications requiring stable anionic charges under varying pH conditions.

Application

• Dispersants & Superplasticizers: A critical monomer for producing high-performance polycarboxylate ether (PCE) superplasticizers used in concrete and cement formulations.
• Ion-Exchange Resins: Serves as a functional monomer for manufacturing strong acid cation exchange resins with high capacity and stability.
• Water-Soluble Polymers: Used in the synthesis of copolymers for water treatment as flocculants and scale inhibitors.
• Textile & Leather Auxiliaries: Imparts anionic character and improves dye uptake and leveling in textile and leather finishing chemicals.
• Paper Sizing & Retention Aids: Incorporated into polymers to improve wet-strength, sizing efficiency, and filler retention in paper manufacturing.
• Enhanced Oil Recovery (EOR): A component in polymers used for mobility control and conformance improvement in oilfield applications.
• Adhesives & Sealants: Modifies acrylic and vinyl adhesive systems to improve water resistance and adhesion to polar substrates.
• Photoresist & Electronic Materials: Used in the development of photoresists and conductive polymers for the electronics industry.

Quality Control

Our Ammonium Vinylbenzenesulphonate is produced under a stringent quality management system. Each batch is analyzed to ensure high purity and consistency, with key parameters including assay, moisture content, and ionic impurity levels monitored. Certificates of Analysis (COA) documenting these results are provided with every shipment. We adhere to relevant industry standards and can support compliance requirements for specific applications upon request.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation. Keep away from strong oxidizing agents.
