Polyakrüülhapet

Polyakrüülhapet is a synthetic polymer derived from acrylic acid. It is a water-soluble polymer that can absorb and retain large amounts of water, making it a superabsorbent polymer. Its chemical structure consists of repeating units of acrylic acid, which are hydrophilic due to the presence of carboxyl groups. This characteristic allows polyakrüülhapet to form a gel when exposed to water, trapping the liquid within its molecular network.

The production of polyakrüülhapet typically involves the polymerization of acrylic acid or its derivatives, such as sodium acrylate. The process can be carried out through various methods, including solution polymerization or suspension polymerization, often initiated by free radicals. The resulting polymer can then be cross-linked to control its absorption capacity and gel strength.

Polyakrüülhapet finds widespread applications due to its unique absorbent properties. It is commonly used in disposable diapers and feminine hygiene products, where it plays a crucial role in moisture management. Other uses include agricultural applications as a soil conditioner to improve water retention, in the production of disposable medical supplies, and as a thickening agent in various industrial products. Its ability to absorb significant volumes of liquid while maintaining structural integrity makes it a versatile material in numerous consumer and industrial goods.
