Polyacrylic acid is a weak anionic polyelectrolyte, whose degree of ionisation is dependent on solution pH. In its non-ionised form at low pHs, PAA may associate with various non-ionic polymers (such as polyethylene oxide, poly-N-vinyl pyrrolidone, polyacrylamide, and some cellulose ethers) and form hydrogen-bonded interpolymer complexes.

Sodium polyacrylate (ACR, ASAP, or PAAS), [1]: 233 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.
It is used primarily for producing oil seals and packaging related to automobiles. Acrylic elastomer can generally be characterized as one of two types. "Old" types include ACM (copolymer of acrylic acid ester and 2-chloroethyl vinyl ether) containing chlorine and ANM (copolymer of acrylic acid ester and acrylonitrile) without chloride. "New ...
Acrylic acid and its esters readily combine with themselves (to form polyacrylic acid) or other monomers (e.g. acrylamides, acrylonitrile, vinyl compounds, styrene, and butadiene) by reacting at their double bond, forming homopolymers or copolymers, which are used in the manufacture of various plastics, coatings, adhesives, elastomers, as well ...
Potassium polyacrylate is a potassium salt of polyacrylic acid with the chemical formula [−CH 2 −CH(CO 2 K)−] n. As a type of superabsorbent polymer, it can absorb hundreds of times its original weight in purified water.
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.
diversity initiative sponsors, and ERG leaders, with recent data to use in their efforts to build an organizational business case for diversity and inclusion. The studies are generally from 2007 to the present, with a few additional significant studies going back to 2004. There is no final version of this tool.
A glass ionomer cement (GIC) is a dental restorative material used in dentistry as a filling material and luting cement, [1] including for orthodontic bracket attachment. [2] Glass-ionomer cements are based on the reaction of silicate glass-powder (calciumaluminofluorosilicate glass [3]) and polyacrylic acid, an ionomer.
