Description

Poly(2-Acrylamido-2-Methyl-1-Propanesulfonic Acid-Co-Acrylonitrile) is a high-performance, water-soluble anionic copolymer designed for demanding industrial applications. This specialized polymer combines the exceptional thermal stability and salt tolerance of AMPS (2-Acrylamido-2-methylpropanesulfonic acid) with the structural integrity of acrylonitrile. It is essential for industries requiring robust rheology modifiers, scale inhibitors, and dispersants under extreme conditions. Key markets include water treatment, oilfield chemicals, textile processing, and advanced material synthesis.

Application

• Oilfield Drilling Fluids: Acts as a high-temperature, high-salinity tolerant viscosifier and fluid loss control agent in challenging wellbore environments.
• Industrial Water Treatment: Serves as a highly effective antiscalant and dispersant for calcium sulfate, barium sulfate, and other inorganic salts in cooling water and reverse osmosis systems.
• Textile & Dyeing Auxiliaries: Used as a leveling agent and dispersant for pigments and dyes, improving color uniformity and fastness.
• Enhanced Oil Recovery (EOR): Functions as a thickening polymer in polymer flooding operations to improve sweep efficiency and oil displacement.
• Paper Manufacturing: Employed as a retention aid and drainage aid to improve paper strength and production efficiency.
• Ceramic & Cement Additives: Acts as a superplasticizer and grinding aid to reduce water content and improve the workability and strength of final products.
• Personal Care & Cosmetics: Utilized as a thickener and stabilizer in formulations like hair gels and creams, offering clarity and salt resistance.
• Coating & Adhesive Formulations: Enhances the stability, rheology, and pigment dispersion in water-based paints and adhesives.
