Potassium Polyacrylateis a molecular formula of[-CH₂-CH(COOK)-]_n repetitive Polymer，Often used in consumer products. It is named because of its strong water absorption.“super-slurper”，Can absorb 200 to 300 times the mass of water.acrylic acidPolymers usually have a negative charge.Although the most widely used agricultural polymers of this type are potassium-neutralized potassium salts, potassium, lithium, and ammonium salts are also viable salts.DissolveDifferent gel states will be formed.

Application

Acrylic acid and its chemical properties have many agricultural uses, including：

1. Aquasorb. (Lock the moisture in plant roots and then release it slowly.)
2. Improve soil conditions. (The gel adhesion after absorbing water effectively improves the quality of sandy soil)
3. Biodegradable. (For example, potassium polyacrylate is naturally degradable: implant gel）
4. Mix with fertilizer.
5. Agricultural and forestry conservation sodium salt, with superior water absorption, is used to retain water in the roots of agriculture and forestry, and its price is lower than potassium polyacrylate. (For example, when used as water-retaining agent for agriculture and forestry ）

References

• Polyacrylamide, a positively charged polymer, can be in the form of linear chain or isomolecule polymerization with monomers such as acrylic acid. Cross-linked polymers polymerized with different amounts of molecules can be used as super absorbent polymers for special purposes.
