polüakrüülhape

Polüakrüülhape (PAA) is a synthetic polymer with the chemical formula (C3H4O2)n. It is a water-soluble polymer that is produced through the polymerization of acrylic acid. PAA is a versatile compound with a wide range of industrial and commercial applications.

One of the primary uses of PAA is as a dispersant. Its ability to prevent particles from aggregating makes it effective in applications such as in paints, coatings, and ceramics. In water treatment, PAA acts as a scale inhibitor, preventing the buildup of mineral deposits in pipes and equipment. It is also employed as a flocculant, aiding in the removal of suspended solids from water.

The absorbency of PAA is another key characteristic. It is used in the production of superabsorbent polymers (SAPs), which can absorb and retain large amounts of liquid relative to their mass. This property makes them valuable in products like diapers, adult incontinence products, and agricultural applications to improve soil water retention.

PAA can also function as a thickener and rheology modifier in various formulations, controlling the flow and consistency of liquids. It finds use in personal care products, detergents, and industrial fluids. The exact properties of PAA can be tailored by controlling the molecular weight and degree of cross-linking during its synthesis, allowing for specific performance characteristics depending on the intended application.
