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, significantly enhancing hydrophilicity, ionic conductivity, and anti-static properties. It is a critical raw material for manufacturers in the water treatment, specialty coatings, and advanced material science sectors seeking to develop high-performance polymers.

Application

• Scale Inhibitor & Dispersant Monomer: A key component in the synthesis of co-polymers for industrial water treatment, preventing scale formation in cooling towers, boilers, and reverse osmosis systems.
• Conductive Polymer Synthesis: Used to create sulfonated polymers for applications requiring ionic conductivity, such as fuel cell membranes, battery binders, and anti-static coatings.
• Hydrophilic Modification Agent: Incorporated into acrylic, polyurethane, or epoxy resin systems to improve surface wetting, adhesion, and moisture management in coatings and films.
• Dye & Pigment Dispersant: Serves as a functional monomer in dispersant polymers for textiles, inks, and paints, improving color strength and stability.
• Enhanced Oil Recovery (EOR): Used in synthesizing polymers for chemical flooding to improve oil displacement efficiency by modifying solution viscosity and rock surface interaction.
• Personal Care & Cosmetic Polymers: Employed in the formulation of hair fixatives, skin care films, and other cosmetic ingredients where mildness and water solubility are required.
