Polyacrylamidomethylpropane sulfonic acid

Polyacrylamidomethylpropane sulfonic acid (commonly known as AMPS or PAMPS) is a highly functional sulfonic acid-containing monomer and polymer. It offers excellent thermal stability, salt tolerance, and thickening properties in aqueous solutions. The polymer provides outstanding viscosity control, lubricity, and film-forming capabilities. It is widely used in water treatment, oilfield, personal care, and industrial applications.
