polyeteenihapoista

Polyeteenihapoista, often translated as poly(acrylic acid) or PAA, is a synthetic polymer composed of repeating acrylic acid monomer units. It is a water-soluble anionic polyelectrolyte, meaning it carries a negative charge when dissolved in water due to the deprotonation of its carboxylic acid groups. The degree of polymerization and the molecular weight of PAA can vary significantly, influencing its physical properties and applications.

PAA is typically produced through the free-radical polymerization of acrylic acid. The resulting polymer is a white, solid powder that readily dissolves in water and polar solvents. Its ability to form gels, its high water absorbency, and its chelating properties are key characteristics.

In its various forms and molecular weights, PAA finds widespread use across numerous industries. It is commonly employed as a dispersant in detergents, preventing the redeposition of dirt. In water treatment, it acts as a scale inhibitor, preventing the formation of mineral deposits in pipes and industrial equipment. Its absorbent properties make it a component in disposable diapers and hygiene products. Furthermore, PAA is utilized in the cosmetic industry as a thickening agent and stabilizer, and in the pharmaceutical sector as a binder and controlled-release agent in drug formulations. The specific properties of PAA, such as its viscosity and charge density, can be tailored for optimized performance in these diverse applications.
