Request SDS →Acrylic acid / 2-acrylamido-2-methylpropanesulfonic acid copolymer (CAS 40623-75-4), AA/AMPS, is a water-soluble anionic acrylic copolymer. Copolymers of this class are used in water treatment as scale inhibitors and dispersants, controlling calcium, phosphate, and iron scale in cooling water, boilers, and reverse-osmosis systems.
Frequently Asked Questions
What is AA/AMPS copolymer used for?
Acrylic acid / 2-acrylamido-2-methylpropanesulfonic acid copolymer (AA/AMPS, CAS 40623-75-4) is a water-soluble anionic acrylic copolymer used in water treatment as a scale inhibitor and dispersant. It controls calcium, phosphate, and iron scale in cooling water, boilers, and reverse-osmosis systems. RawSource supplies it for water-treatment formulation.
How does AA/AMPS work as a scale inhibitor?
The copolymer combines carboxylate (acrylic acid) and sulfonate (AMPS) groups, which adsorb onto mineral nuclei and disperse particulate foulants, suppressing calcium, phosphate, and iron scale and improving tolerance in high-hardness and high-iron waters. Recommended dosage depends on system water chemistry; refer to the technical data sheet.
Is AA/AMPS copolymer water soluble?
Yes. AA/AMPS is a water-soluble anionic copolymer, typically supplied as an aqueous solution for direct dosing into water-treatment formulations. Active solids are confirmed on the Certificate of Analysis.
What is the CAS number and identity of the AA/AMPS copolymer?
The copolymer is identified by CAS 40623-75-4 (acrylic acid / 2-acrylamido-2-methylpropanesulfonic acid copolymer). Molecular weight range and active solids vary by grade and are defined on the lot CoA; specify your target grade when ordering.
How is bulk AA/AMPS copolymer packaged and quoted?
RawSource supplies water-treatment polymers in drums, IBCs/totes, and bulk to formulators. Active solids, packaging, lead time, and pricing are quoted per order; submit volume and destination for a bulk quote, with SDS and CoA on shipment.
