Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2-). It has a linear-chain structure. It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated.
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).

Polyacrylamide gel electrophoresis is a powerful tool used to analyze RNA samples. When polyacrylamide gel is denatured after electrophoresis, it provides information on the sample composition of the RNA species. [1] Hydration of acrylonitrile results in formation of acrylamide molecules (C 3 H 5 NO) by nitrile hydratase. [2]
Acrylamide (or acrylic amide) is an organic compound with the chemical formula CH 2 =CHC(O)NH 2.It is a white odorless solid, soluble in water and several organic solvents. From the chemistry perspective, acrylamide is a vinyl-substituted primary amide (CONH 2).
Other materials are also used to make a superabsorbent polymer, such as polyacrylamide copolymer, ethylene maleic anhydride copolymer, cross-linked carboxymethylcellulose, polyvinyl alcohol copolymers, cross-linked polyethylene oxide, and starch grafted copolymer of polyacrylonitrile to name a few. The latter is one of the oldest SAP forms created.
The synthesis of poly(N-isopropylacrylamide) began with the synthesis of the acrylamide monomer by Sprecht in 1956. [13]In 1957, Shearer patented the first application for what would be later identified as PNIPA for the use as a rodent repellent. [14]
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.
