Product Overview
AMPS, short for 2-Acrylamido-2-methylpropane sulfonic acid, Alias: ATBS, CAS No.:15214-89-8, EINECS No.: 258-321-1. It is a reactive water-soluble acrylic monomer with sulfonic acid functional groups. Its unique molecular structure endows polymers with permanent anionic charge, excellent anti-hydrolysis performance, high temperature resistance and strong anti-salt capability compared with common acrylamide polymers.
AMPS can undergo homopolymerization or copolymerize with acrylamide, acrylic acid, acrylonitrile and other vinyl monomers to produce multifunctional water-soluble polymers. It serves as a key raw material for manufacturing scale inhibitors, dispersants, drilling fluid additives, thickeners and superabsorbent resins.

Key Properties & Advantages
■ Excellent thermal stability and high salt resistance, suitable for high-temperature and high-salinity working environments
■ Superior hydrolytic stability under acidic, neutral and weakly alkaline conditions
■ Strong hydrophilicity and anionic characteristics, improving polymer dispersion and adsorption capacity
■ Good copolymerization activity with various acrylic monomers
■ Low residual impurities, stable quality for long-term polymer synthesis
Main Applications
■ Oilfield Chemicals: AMPS-based polymers are used in water-based drilling fluids, fracturing fluids, cementing additives and EOR polymer flooding. They act as fluid loss control agents, clay inhibitors and friction reducers to stabilize wellbore under HT/HS (high temperature high salinity) reservoir conditions.
■ Industrial Water Treatment: AMPS copolymers are mainstream scale inhibitors and dispersants for circulating cooling water, boiler water and wastewater treatment. Effectively suppress calcium carbonate, calcium sulfate and phosphate scale; disperse suspended solids and sludge.
■ Superabsorbent Polymers (SAP): Improve salt absorbency of SAP used in hygiene products, agricultural water retention agents and industrial gel materials.
■ Textile & Printing Auxiliaries: Modify acrylic fiber; enhance dye uptake, antistatic property and washing fastness for synthetic fabrics.
■ Coatings, Adhesives & Construction Chemicals: Applied in waterborne latex coatings, pressure-sensitive adhesives and concrete superplasticizers to boost dispersion stability, adhesion strength and workability.
■ Other Fields:Papermaking retention aids, daily chemical thickeners, medical hydrogels and biomaterial intermediates.
