Acrylic acid-hydroxypropyl acrylate copolymer

Acrylic acid-hydroxypropyl acrylate copolymer (CAS 55719-33-0), also referenced commercially as AA/HPA, is a water-soluble anionic polymer used in industrial water management and process chemistry.

Where is Acrylic acid-hydroxypropyl acrylate copolymer used?

• Water treatment: scale inhibitor, dispersant and corrosion control agent in hard water, mineral slurries and process fluids
• Oilfield and industrial water treatment: inhibits calcium carbonate and calcium sulfate deposits in cooling towers, boilers and injection water systems
• Textile and paper processing: disperses pigments and controls rheology
• Coating formulations: improves uniformity and reduces equipment fouling
• Mining and mineral processing: flocculant aid that accelerates solid-liquid separation in tailings and ore slurry circuits
• It also acts as a threshold inhibitor in low-dose antiscalant programs.

Commercial specifications

• Aqueous solution, typically 40–50% active content
• Packaging: drums, IBC totes and bulk tanker supply
