Polüakrüülhapped

Polüakrüülhapped are polymers derived from acrylic acid. They are synthetic compounds that form long chains of repeating acrylic acid units. The properties of polyacrylic acids can vary depending on their molecular weight and degree of polymerization. They are typically water-soluble, especially when neutralized.

These polymers are known for their ability to absorb and retain large amounts of water. This characteristic makes them highly effective as superabsorbent polymers (SAPs). When exposed to water, the carboxylic acid groups along the polymer chain become ionized, attracting water molecules and forming a gel-like substance. This water-absorbing capacity is significantly higher than that of ordinary hydrophilic polymers.

Polüakrüülhapped find widespread application in various industries due to their unique properties. They are extensively used in disposable diapers and other personal hygiene products for their absorbency. In agriculture, they are employed as soil conditioners to improve water retention, reduce irrigation needs, and enhance plant growth. They also serve as thickeners and stabilizers in cosmetics, pharmaceuticals, and industrial formulations. Additionally, their chelating properties allow them to bind metal ions, making them useful in water treatment and detergent formulations to prevent scale formation. The production of polyacrylic acids involves the polymerization of acrylic acid monomers, often through free-radical polymerization.
