  2. Swelling capacity - Wikipedia

    en.wikipedia.org/wiki/Swelling_capacity

    A small amount of superabsorbent polymer material is taken (0.1g) and it is placed in the beaker. 100 ml of deionized water is poured into the beaker. After 20 min the swollen polymer was separated by using [filter paper] By weighing the polymer, one can find the swollen capacity of the SAP material. [3]

  3. Superabsorbent polymer - Wikipedia

    en.wikipedia.org/wiki/Superabsorbent_polymer

    Superabsorbent polymer: Polymer that can absorb and retain extremely large amounts of a liquid relative to its own mass. [5] Notes: The liquid absorbed can be water or an organic liquid. The swelling ratio of a superabsorbent polymer can reach the order of 1000:1. Superabsorbent polymers for water are frequently polyelectrolytes.

  4. Sodium polyacrylate - Wikipedia

    en.wikipedia.org/wiki/Sodium_polyacrylate

    This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 times its mass in water. Sodium polyacrylate is an anionic polyelectrolyte [2] with negatively charged carboxylic groups in the main chain. It is a polymer made up of chains of acrylate compounds. It contains sodium, which gives it the ability to absorb large amounts of water.

  5. Solution polymerization - Wikipedia

    en.wikipedia.org/wiki/Solution_polymerization

    The reaction results in a polymer which is also soluble in the chosen solvent. Heat released by the reaction is absorbed by the solvent, reducing the reaction rate. Moreover, the viscosity of the reaction mixture is reduced, preventing autoacceleration at high monomer concentrations. A decrease in viscosity of the reaction mixture by dilution ...

  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. Suspension polymerization - Wikipedia

    en.wikipedia.org/wiki/Suspension_polymerization

    In polymer chemistry, suspension polymerization is a heterogeneous radical polymerization process that uses mechanical agitation to mix a monomer or mixture of monomers in a liquid phase, such as water, while the monomers polymerize, forming spheres of polymer. [2] The monomer droplets (size of the order 10-1000 μm) are suspended in the liquid ...

    en.wikipedia.org/wiki/Polydextrose

    Polydextrose is a synthetic polymer of glucose. [1] It is a food ingredient classified as soluble fiber by the US FDA as well as Health Canada, as of April 2013. It is frequently used to increase the dietary fiber content of food, to replace sugar, and to reduce calories and
