Sodium Vinyl Sulfonate
CAS Number: 3039-83-6
Sodium vinyl sulfonate (SVS) is a water-soluble anionic functional monomer used to introduce sulfonate groups into polymer backbones. Sulfonate groups provide strong anionic charge, hydrophilicity, electrolyte tolerance, and enhanced latex colloidal stability. SVS is used as a co-monomer in emulsion polymerization, ion-exchange resin synthesis, and antistatic polymer coatings.

Applications
- Emulsion polymer colloidal stabilization co-monomer
- Strong cation-exchange resin functional group introduction
- Antistatic polymer coating and fiber treatment
- Sulfonated polyester and polyurethane water-dispersible resins
- Electrolyte-stable latex for construction and adhesive applications
Key Features
- Strong acid sulfonate group remains ionized across the entire pH range for consistent charge
- Improves colloidal stability of latex under high electrolyte and freeze-thaw conditions
- Imparts antistatic properties to polyester and polyamide fibers and films
- Low sulfate impurity avoids premature coagulation in sensitive emulsion systems
