2. Superabsorbent polymer - Wikipedia

   en.wikipedia.org/wiki/Superabsorbent_polymer

   Superabsorbent polymer: Polymer that can absorb and retain extremely large amounts of a liquid relative to its own mass. [5] Notes: The liquid absorbed can be water or an organic liquid. The swelling ratio of a superabsorbent polymer can reach the order of 1000:1. Superabsorbent polymers for water are frequently polyelectrolytes.

3. Water crystal gel - Wikipedia

   en.wikipedia.org/wiki/Water_crystal_gel

   Hydrated water gel, or water beads. Water crystal gel or water beads or gel beads is any gel which absorbs and contains a large amount of water.Water gel is usually in spherical form and composed of a water-absorbing superabsorbent polymer (SAP, also known as slush powder in dry form) such as a polyacrylamide (frequently sodium polyacrylate).

4. Solution polymerization - Wikipedia

   en.wikipedia.org/wiki/Solution_polymerization

   The reaction results in a polymer which is also soluble in the chosen solvent. Heat released by the reaction is absorbed by the solvent, reducing the reaction rate. Moreover, the viscosity of the reaction mixture is reduced, preventing autoacceleration at high monomer concentrations. A decrease in viscosity of the reaction mixture by dilution ...

5. Polymer clay - Wikipedia

   en.wikipedia.org/wiki/Polymer_clay

   Oven-hardenable PVC plastisol, "liquid polymer clay," is a complement to polymer clay that can be used as an adhesive to combine pieces, or to create various effects. Pigments, chalk pastel, and regular polymer clay can be added to make colored liquid clay. The liquid can also be poured into molds to produce cast parts. [citation needed]

6. Potassium polyacrylate - Wikipedia

   en.wikipedia.org/wiki/Potassium_polyacrylate

   As a type of superabsorbent polymer for plants (Ag-SAP), potassium polyacrylate can increase moisture availability to plants. It mixes with soil to increase the soil’s capacity for holding water (with water gel form which stay in soil for months [2]) and making it available to plants. This improved soil readily releases moisture, along with ...

7. Sodium polyacrylate - Wikipedia

   en.wikipedia.org/wiki/Sodium_polyacrylate

   This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 times its mass in water. Sodium polyacrylate is an anionic polyelectrolyte [2] with negatively charged carboxylic groups in the main chain. It is a polymer made up of chains of acrylate compounds.

8. Swelling capacity - Wikipedia

   en.wikipedia.org/wiki/Swelling_capacity

   A small amount of superabsorbent polymer material is taken (0.1g) and it is placed in the beaker. 100 ml of deionized water is poured into the beaker. After 20 min the swollen polymer was separated by using [filter paper] By weighing the polymer, one can find the swollen capacity of the SAP material. [3]

9. Hydrogel agriculture - Wikipedia

   en.wikipedia.org/wiki/Hydrogel_agriculture

   Superabsorbent polymers can be used to release phosphate fertiliser slowly, by making an ester bond between polyvinyl alcohol and phosphoric acid. A polymer/clay superabsorbent composite material made by attaching acrylamide to finely powdered attapulgite (a fuller's earth clay) shows promise for its excellent water retention and low cost ...
