Description

Bis(3-Sulfopropyl) Itaconate, Dipotassium Salt is a high-purity, water-soluble anionic monomer derived from itaconic acid. This compound is valued for its ability to introduce sulfonate functional groups into polymer chains, imparting enhanced hydrophilicity, dispersancy, and anti-scaling properties. It is primarily sought by formulators and researchers in the water treatment, textile processing, and advanced material synthesis industries for developing high-performance copolymers and surface modifiers.

Application

• Scale Inhibitor Monomer: A key building block in copolymers for industrial water treatment systems to prevent calcium carbonate and sulfate scale.
• Dispersant Synthesis: Used in the production of polycarboxylate-based dispersants for cement, pigments, and ceramic slurries.
• Textile Auxiliaries: Incorporated into polymers for dye-leveling agents, anti-static finishes, and soil-release coatings on fabrics.
• Enhanced Oil Recovery (EOR): Serves as a comonomer in polymers designed for viscosity modification and improved oil displacement in EOR applications.
• Paper Sizing Agents: Contributes to the development of internal sizing agents that improve paper water resistance and strength.
• Personal Care Polymers: Used in the synthesis of hair fixatives and skin care polymers where mildness and water solubility are required.
• Conductive Polymers: Acts as a dopant or comonomer in the research and development of conductive polymer films and hydrogels.
• Adhesive & Coating Modifiers: Imparts improved adhesion to wet surfaces and moisture resistance in acrylic and polyurethane-based formulations.
