sodium polyacrylate

Replies: Sodium polyacrylate does absorb a large amount of water.

If forever, is there any way to separate water from sodium polyacrylate after it has been mixed?

Sodium polyacrylate can absorb around 300 times its weight in distilled water.

Why do you want to avoid sodium polyacrylate?

Sodium polyacrylate is difficult to prepare outside the lab since it involves many chemical reaction steps.

Replies: Sodium polyacrylate will hold on to water (at room temperature) indefinitely for all practical time frames.

Type "sodium polyacrylate" into the Google search engine.

However, it does not "gel" as well as sodium polyacrylate, but instead forms thick solutions.

Vince Calder Sodium polyacrylate, like the stuff used in baby diapers, can hold on to a lot of water.

A powdery chemical absorbent called sodium polyacrylate is incorporated into the fabric of the garment.

Sodium polyacrylate is anionic polyelectrolytes with negatively charged carboxylic groups in the main chain.

Upon further analysis these proved to be sodium polyacrylate granules, a kind of superabsorbent polymer with a variety of common (including agricultural) uses.

Sodium polyacrylate and other derivatives of polyacrylic acid have a wide variety of commercial and industrial uses that include:

This process is one of two used in the production of sodium polyacrylate, a superabsorbent polymer used in disposable diapers.

Water gel is usually composed of a water-absorbing polymer such as a polyacrylamide (frequently Polymethylacrylate or Sodium Polyacrylate).

To prevent the particles from aggregating, some sort of stabilizing agent or stabilizer that sticks to the nanoparticle surface is usually added, such as sodium polyacrylate.

Common ingredients are e.g. polyvinyl alcohol, sodium polyacrylate, acrylate polymers and copolymers with an abundance of hydrophilic groups.

For many applications PAAs are used in form of alkali metal or amonium salts e.g. sodium polyacrylate.

Best wishes, Tom Collins Hi Lorhena, Sodium polyacrylate is a polymer that has many chemical structures that naturally attract water molecules.

The flushable insert contents include elemental-Chlorine-free, farmed tree fluff pulp and super absorber called SAP (sodium polyacrylate).

Vince Calder Lorhena, Sodium polyacrylate is a polymer (a long chain molecule) with ionic groups (negative charges with accompanying positively charged sodium ions) all along its length.

This material can be synthesized in an environmentally friendly way and is biodegradeable, thus it is a green alternative to several materials such as sodium polyacrylate used in disposable diapers and agriculture.

Sodium polyacrylate, also known as waterlock, is a sodium salt of polyacrylic acid with the chemical formula [-CH-CH(COONa)-] and broad application in consumer products.

Sodium polyacrylate, the gel-like absorbent in the pad, was removed from use in tampons in 1985 due to its possible link to toxic shock syndrome, a rare life threatening bacterial infection [source: Citrinbaum].

A CDC/NIOSH bulletin (URL below) advises determining the water content of sodium polyacrylate by heating for 16 hours at 130 C. This suggests the polymer is stable under those conditions.
