Also, sodium polyacrylate is a low-cost, non-toxic, and biocompatible option for water purification to recover metal ions. A study demonstrated that a sodium polyacrylate composite had high adsorption and desorption efficiency, implying that sodium polyacrylate can be recycled and reused as an effective absorbent for Cu(II) recovery.

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.
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.
Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. [1] Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide. [12] [13] Considerable effort is made to scavenge traces of acrylamide from the polymer intended for use near food. [1]
The polymer is used as the sodium salt (see: sodium polyacrylate). [1] Use. Isomers of the repeating unit in polyaspartic acid.

Indiana may not have been one of the very best teams in college football, but a team that goes 11-1 in a power conference was always going to be a foregone conclusion to make the 12-team College ...
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).
