  • Applications

    Sodium methallylsulfonate (CAS 1561-92-8) is a water-soluble vinyl sulfonate monomer used primarily as a comonomer to synthesize sulfonated polymers and ion-containing hydrogels. These polymers are employed in ion-exchange resins and other water-treatment polymers. It is also used to prepare polymeric dispersants and thickeners for coatings and inks, improving dispersion and rheology. In adhesive formulations, it provides ionic functionality that can enhance bonding in certain systems. It may serve as an intermediate in the synthesis of specialty cleaning and dispersant polymers for industrial formulations.
