Description

Benzenesulfonic Acid, 4-Ethenyl-, Sodium Salt, Polymerwith 2-Propenenitrile is a synthetic, water-soluble polymer derived from the copolymerization of sodium 4-vinylbenzenesulfonate and acrylonitrile. This compound is valued for its anionic character and high thermal stability, making it an effective dispersant and rheology modifier in demanding industrial formulations. It is primarily utilized in sectors requiring precise control over particle suspension and viscosity, such as advanced ceramics, water treatment, and textile processing.

Application

• Dispersing Agent for inorganic pigments and fillers in coatings, inks, and advanced ceramic slurries.
• Rheology Modifier in water-based systems to control viscosity and prevent settling.
• Scale Inhibitor in industrial water treatment and cooling tower applications.
• Textile Auxiliary used in dyeing and finishing processes to improve levelness and fastness.
• Additive for Oilfield Chemicals, functioning as a fluid loss control agent in drilling muds.
• Stabilizer in emulsion polymerization for the production of specialty latexes.
