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.
Polyacrylamides is a category of polymers whose monomers are acrylamides. Some important examples are: Polyacrylamide, the original homologue; Poly(N-isopropylacrylamide), i.e. the well-known PNIPAM or PNIPAAm
Polyacrylamide gel electrophoresis (PAGE) is a technique widely used in biochemistry, forensic chemistry, genetics, molecular biology and biotechnology to separate biological macromolecules, usually proteins or nucleic acids, according to their electrophoretic mobility. Electrophoretic mobility is a function of the length, conformation, and ...
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).
Under basic conditions, MBA reacts further with formaldehyde at the amide nitrogen to give N-hydroxymethyl,N,N′-methylenebisacrylamide.Nucleophiles such as alcohols, amines, or thiols add across the activated vinyl groups, giving mixtures of mono- and disubstituted products.
2-Acrylamido-2-methylpropane sulfonic acid (AMPS [1]) was a Trademark name by The Lubrizol Corporation.It is a reactive, hydrophilic, sulfonic acid acrylic monomer used to alter the chemical properties of wide variety of anionic polymers.
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] Early work was piqued by theoretical curiosity of the material properties of PNIPA.
Solution-based polymerization is commonly used today for SAP manufacture of co-polymers, particularly those with the toxic acrylamide monomer. This process is efficient and generally has a lower capital cost base. The solution process uses a water-based monomer solution to produce a mass of reactant polymerized gel.
