  2. Polyacrylamide - Wikipedia

    en.wikipedia.org/wiki/Polyacrylamide

    Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1]

  3. Polymer soil stabilization - Wikipedia

    en.wikipedia.org/wiki/Polymer_soil_stabilization

    The structure of polyacrylamide (PAM), a common synthetic polymer flocculating agent used to increase aggregate sizes in clay-rich soils. Soil characteristics that have been altered by addition of polymers include compressive strength, volume stability, hydraulic durability, and conductivity. [5]

  4. Cationic polymerization - Wikipedia

    en.wikipedia.org/wiki/Cationic_polymerization

    cationic polymerization: An ionic polymerization in which the kinetic-chain carriers are cations. [ 1 ] In polymer chemistry , cationic polymerization is a type of chain growth polymerization in which a cationic initiator transfers charge to a monomer , which then becomes reactive.

  6. Polyacrylic acid - Wikipedia

    en.wikipedia.org/wiki/Polyacrylic_acid

    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. [17]

  7. Polyacrylamide gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Polyacrylamide_gel...

    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 ...

  8. Coomassie brilliant blue - Wikipedia

    en.wikipedia.org/wiki/Coomassie_brilliant_blue

    The formation of the complex stabilises the negatively charged anionic form of the dye, producing the blue colour, even under acid conditions when most of the molecules in solution are in the cationic form. [8] This is the basis of the Bradford assay, which quantifies protein by Coomassie brilliant blue dye binding. The binding of the dye to a ...

  9. PolyDADMAC - Wikipedia

    en.wikipedia.org/wiki/PolyDADMAC

    The molecular weight of polyDADMAC is typically in the range of hundreds of thousands of grams per mole, and even up to a million for some products. PolyDADMAC is usually delivered as a liquid concentrate having a solids level in the range of 10 to 50%. It is a high charge density cationic polymer.
