Polyacrylic acid - Wikipedia
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 .

Polyacrylic Acid - an overview | ScienceDirect Topics
Polyacrylic acid (PAA) is a synthetic high-molecular weight polymer of acrylic acid. PAA is an anionic polymer, that is, PAA side chains are ionized at neutral pH and bear a negative charge. Due to this, PAAs are able to absorb and retain water and swell many times compared to their original volume.

What is Poly(Acrylic Acid)(PAA)? - ChemicalBook
2024年5月29日 · Poly(acrylic acid) (PAA) is a polymer of acrylic acid, which has a carboxylic group on each monomer unit. This polymer becomes a polyelectrolyte in water via dissociation of the acid groups.
Poly(acrylic acid): Uses, Synthesis and Solubility - ChemicalBook
2020年7月23日 · Poly (acrylic acid), also known as PAA, is a derivative of acrylic acid which when in a water solution at neutral pH is an anionic polymer. Partially or wholly deprotonated PAAs are polyelectrolytes, with the ability to absorb and hold water while expanding to numerous times their original volume.

Poly (acrylic acid) (PAA) is hygroscopic, brittle and colorless in nature with Tg at nearly 106 o C. At temperatures above 200 to 250 o C, it loses water and becomes an insoluble crosslinked polymer anhydride. Solubility of dried PAA in water increases with rise in temperatures. Concentrated solutions of PAA in water is thixotropic in nature.
Polyacrylic acid is a large-molecular-weight compound called a polymer, which consists of small repeating units called monomers. The polyacrylate polymer used in diapers is constructed from the acrylic acid and sodium acrylate monomers.
