  • Applications

    2-Acrylamido-2-methyl-1-propanesulfonic acid, CAS number: 15214-89-8, is a sulfonic acid-containing monomer used to prepare water-soluble polymers and hydrogels; it is commonly copolymerized with acrylamide and other vinyl monomers to introduce sulfonic acid groups, delivering high hydrophilicity, ionic character, and improved salt tolerance; real-world applications include: (1) making superabsorbent polymers for hygiene products; (2) thickeners and rheology modifiers in paints, coatings, inks, cosmetics, and household cleaners; (3) polymeric ingredients in cosmetics and personal care products as thickening and stabilizing agents; (4) oilfield polymers for fracturing fluids and enhanced oil recovery due to viscosity enhancement in high-salinity environments; (5) water-treatment polymers for flocculation and dispersion control; and (6) detergent and cleaning formulations as polymer building blocks to improve dispersion and stability.
