sodium polyacrylate - wikipedia

Sodium polyacrylate - Wikipedia

Sodium polyacrylate, also known as waterlock, is a sodium salt of polyacrylic acid with the chemical formula [−CH 2 −CH (CO 2 Na)−] n and has broad applications in consumer products. This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 times its mass in water. Sodium polyacrylate is an anionic polyelectrolyte with

Thermal stability of montmorillonite polyacrylamide and

Highlights Clay mineral/poly(sodium acrylate-co-acrylamide) hydrogel nanocomposites were studied. A relatively high amount of raw montmorillonite was introduced to the CPN. Effect of polymer composition on the thermal stability of CPN was observed. Swelling and adsorption capacity was determined by the hydrogel type. High adsorption efficiency in Fe(III) removal was achieved for the studied CPN.

Swelling performance of sodium polyacrylate and poly

While the sodium polyacrylate exhibited a similar swelling behaviour, at 25 °C it demonstrated its highest absorbency (293 g/g) which decreased (264 g/g) at 50 °C. For both samples at 75 °C and higher, their polymer networks collapsed significantly leading to a release of absorbed water.

Polyacrylamide contains small amounts of unreacted acrylamide. [3] In water-based solutions, some of the remaining acrylamide can be stripped out but removing acrylamide from solid forms is more difficult. In both cases, some acrylamide is likely to remain. [4]

Water Soluble Polymer Flocculants: Synthesis

Sodium alginate is extracted from brown green algae and seaweeds, which binds 200–300-fold weight of water to form gels. The ratio of d-mannuronic acid and l-guluronic acid and their sequences determine the alginate properties. Sodium alginate grafted with another functional polymer has been extensively used as a flocculant.

TGA analysis shows that sodium alginate had three decomposition temperatures: 103 °C due to dehydration, 212 °C associated with the destruction of glycosidic bonds, and 426 °C due to conversion of alginate into Na 2 CO 3. The copolymer presents four processes at different temperatures, i.e., evaporation of alcohol at 65 °C, decomposition of

The white granules that remain are sodium polyacrylate, which makes the diaper super-absorbent. Using a dropper, slowly add water to the granules and watch the gel instantly form. Show the students a bottle of sodium polyacrylate and ask them to predict how many super-absorbent diapers could be made with this amount of powder. 3.
