Sodium vinylsulfonate
Sodium vinylsulfonate (CAS: 3039-83-6) is a reactive anionic monomer comprising a polymerizable vinyl group and a strongly hydrophilic sulfonate group. Supplied typically as an aqueous solution, it readily copolymerizes with acrylamide, acrylic esters, styrene, and other vinyl monomers, introducing permanent anionic charge and exceptional water solubility into the resulting polymers. These copolymers serve as high-performance dispersants for pigments and minerals, scale inhibitors in water treatment, dye-leveling agents in textile processing, and soil conditioners in agriculture. The polymer’s electrolyte tolerance and thermal stability make it effective in harsh process conditions where conventional polyelectrolytes fail. In personal care, sulfonate-containing copolymers provide conditioning and fixative benefits. With its dual functionality of polymerizability and ionic character, sodium vinylsulfonate is a valuable monomer for designing advanced water-soluble polymers across industrial and consumer applications.
– Dispersant Polymer Synthesis: Used as a comonomer to produce highly effective dispersants for pigments, fillers, and mineral slurries in coatings and ceramics.
– Water Treatment Polymers: Serves as a building block for scale inhibitors and dispersants tolerating high electrolyte and temperature conditions.
– Textile Processing: Applied in dye-leveling agents and anti-backstaining additives improving color uniformity and wash performance.
– Soil Conditioning: Incorporated into polymer soil amendments that improve water retention and reduce erosion in agricultural applications.
