Description

Poly(Styrene-Co-2-Acrylamido-2-Methyl Propane Sulfonic Acid), Sodium Salt is a high-performance, water-soluble anionic copolymer designed for demanding industrial applications. This specialized material combines the structural integrity of polystyrene with the exceptional ionic conductivity and hydrophilicity of the sulfonated acrylamide monomer. It is essential for industries requiring advanced rheology modifiers, dispersants, or ion-exchange materials with robust chemical stability. Key sectors utilizing this polymer include water treatment, enhanced oil recovery, specialty coatings, and advanced material synthesis.

Application

• Enhanced Oil Recovery (EOR): Acts as a viscosifier and mobility control agent in polymer flooding to improve sweep efficiency and oil displacement.
• Water Treatment & Scale Inhibition: Functions as a highly effective antiscalant and dispersant for inorganic salts in industrial cooling water, boiler water, and reverse osmosis systems.
• Dispersant for Inorganic Pigments & Fillers: Provides superior stabilization and dispersion for calcium carbonate, clay, titanium dioxide, and other particulates in slurry formulations.
• Rheology Modifier for Coatings & Adhesives: Modifies viscosity and improves the application properties of aqueous-based paints, coatings, and adhesive systems.
• Ion-Exchange Resins & Membranes: Serves as a key component or precursor in the manufacture of cation-exchange materials for separation and purification processes.
• Concrete Admixture: Used as a superplasticizer or water-reducing agent to improve the workability and strength of concrete mixes.
• Textile & Paper Processing: Employed as a dye-leveling agent, anti-redeposition agent, or retention aid in textile and paper manufacturing.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and caking. Store away from incompatible materials.
