Poly(acrylic acid)
Poly(acrylic acid) (PAA) with CAS number 9003-01-4 is a synthetic, water-soluble polymer. It is a weak acid commonly supplied as an aqueous solution. Its properties as a polyelectrolyte and thickening agent lend themselves to diverse industrial and scientific applications, including water treatment, dispersants, and as a component in gels and coatings. Tech Serve Solutions supplies this versatile polymer for research and industrial use.
Water Treatment
Poly(acrylic acid) acts as an effective scale inhibitor and dispersant in water treatment applications, preventing the buildup of mineral deposits in industrial systems and boilers.
Dispersant and Thickener
In various formulations, PAA functions as a highly efficient dispersant for particles and as a thickening agent to control viscosity in products like paints, adhesives, and cosmetics.
Materials Science
Its polymeric nature and chemical structure make it a valuable component in the development of novel materials, including hydrogels, coatings, and specialized membranes for scientific research.
Ion Exchange and Chelation
The carboxylic acid groups in PAA enable it to bind metal ions, making it useful in ion-exchange resins and as a chelating agent in various chemical processes.
