Description

2-Acrylamido-2-methyl-1-propanesulfonic acid (CAS 15214-89-8 ), commercially known as AMPS, is a reactive sulfonic acid monomer used to engineer performance polymers across industrial and specialty chemical markets. Its strong anionic character makes it a preferred building block for water-soluble and hydrogel polymer systems where charge density and hydrolytic stability are critical sourcing considerations for manufacturers. In water treatment, AMPS is copolymerized into scale inhibitors and dispersants that control mineral deposition in cooling towers, boilers, and reverse osmosis systems to maintain operational efficiency. Personal care formulators incorporate AMPS-based polymers as rheology modifiers and film formers in styling gels, skin creams, and sunscreen carriers to enhance product texture and application performance. Textile and paper processing operations use AMPS copolymers for surface sizing, wet-strength improvement, and dye fixation, ensuring high-quality finishes and durability in the final consumer products. In oilfield applications, AMPS serves as a key monomer in fluid loss control additives and friction reducers used in drilling and enhanced oil recovery formulations for demanding environments. AMPS is supplied as a white crystalline powder and as an aqueous solution, typically at 50% concentration. Standard grades include technical and industrial purity levels suited for polymer synthesis. Specialty grades meeting higher purity thresholds are available for personal care and cosmetic polymer applications, ensuring compliance with rigorous industry safety and performance requirements.
