In the agricultural industry, sodium polyacrylate is used to help plants retain moisture in the soil. [13] It can act as a water reservoir for plants and is commonly used by florists to keep flowers fresh. Furthermore, the use of sodium polyacrylate for growing domestic fruit and vegetables has been approved by the U.S. Department of Agriculture.
Superabsorbent polymers are now commonly made from the polymerization of acrylic acid blended with sodium hydroxide in the presence of an initiator to form a poly-acrylic acid sodium salt (sometimes referred to as sodium polyacrylate). This polymer is the most common type of SAP made in the world today.
Polyacrylic acid is a weak anionic polyelectrolyte, whose degree of ionisation is dependent on solution pH. In its non-ionised form at low pHs, PAA may associate with various non-ionic polymers (such as polyethylene oxide, poly-N-vinyl pyrrolidone, polyacrylamide, and some cellulose ethers) and form hydrogen-bonded interpolymer complexes.

Dosage of defoamer. A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer are often used interchangeably. Strictly speaking, defoamers eliminate existing foam and anti-foamers prevent the formation of further foam.
Polyacrylate emulsion, water-borne coating, are used as binder for outdoor and indoor "latex" house paints.; Acrylic paints as artist paints.; Acrylic fibre.; Sodium polyacrylate water-soluble thickeners, a polymer for the production of the Superabsorbent polymer (SAP) used in disposable diapers due to its high absorbency per unit mass.
For instance, they can be used to destabilize a colloidal suspension and to initiate flocculation (precipitation). They can also be used to impart a surface charge to neutral particles, enabling them to be dispersed in aqueous solution. They are thus often used as thickeners, emulsifiers, conditioners, clarifying agents, and even drag reducers.
Polycarboxylates are organic compounds with several carboxylic acid groups. Butane-1,2,3,4-tetracarboxylate is one example. Often, polycarboxylate refers to linear polymers with a high molecular mass (M r ≤ 100 000) and with many carboxylate groups. They are polymers of acrylic acid or copolymers of acrylic acid and maleic acid.
Acrylic acid (IUPAC: prop-2-enoic acid) is an organic compound with the formula CH 2 =CHCOOH. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group connected directly to a carboxylic acid terminus. This colorless liquid has a characteristic acrid or tart smell. It is miscible with water, alcohols, ethers, and chloroform ...
