Application
Sodium salt of poly (acrylic acid) may be used as a major component of non glare coatings for headlights.It acts as an antiscaling agents.It′s effect of the salt on the crystal (Cu and MS metals) formation was studied. General applications of these superabsorbents are in many fields such as agriculture and horticulture, sanitary goods, sealing composites, component of moisture barrier tapes and coatings, humidity control, gel actuators. and medicine for drug-delivery systems.
General description
Sodium salt of poly(acrylic acid) is a superabsorbent polymer. Superabsorbents are composed of crosslinked networks of hydrophilic polymers. It can absorb and retain a large capacity of water based fluids, the release of the absorbed fluids is tough even under an applied pressure. Absorption capacity is inversely proportional to salt concentration and applied load.They are formed via solution or inverse-suspension polymerization techniques. †
