AA-AMPSA (Cat No.: M015833) refers to a copolymer composed of acrylic acid (AA) and 2-acrylamido-2-methylpropane sulfonic acid (AMPSA), known for its excellent water solubility, thermal stability, and ionic conductivity. This anionic copolymer is widely used in water treatment, oilfield applications, and scale inhibition due to its strong dispersing and chelating properties. The sulfonic acid groups enhance performance under high salinity and temperature, while acrylic acid units improve binding and film formation. AA-AMPSA is valuable in formulations requiring robust performance in harsh industrial environments.
