  2. Sodium polyacrylate - Wikipedia

    en.wikipedia.org/wiki/Sodium_polyacrylate

    Sodium polyacrylate (ACR, ASAP, or PAAS), [1]: 233 also known as waterlock, is a sodium salt of polyacrylic acid with the chemical formula [−CH 2 −CH(CO 2 Na)−] n and has broad applications in consumer products.

  3. Defoamer - Wikipedia

    en.wikipedia.org/wiki/Defoamer

    Dosage of defoamer. A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer are often used interchangeably. Strictly speaking, defoamers eliminate existing foam and anti-foamers prevent the formation of further foam.

  4. 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]

  5. Superabsorbent polymer - Wikipedia

    en.wikipedia.org/wiki/Superabsorbent_polymer

    Superabsorbent polymers are now commonly made from the polymerization of acrylic acid blended with sodium hydroxide in the presence of an initiator to form a poly-acrylic acid sodium salt (sometimes referred to as sodium polyacrylate). This polymer is the most common type of SAP made in the world today.

  6. Acrylate polymer - Wikipedia

    en.wikipedia.org/wiki/Acrylate_polymer

    Acrylic elastomer is a general term for a type of synthetic rubber whose primary component is acrylic acid alkyl ester (ethyl or butyl ester). [3] Acrylic elastomer possesses characteristics of heat and oil resistance, with the ability to withstand temperatures of 170–180 °C. It is used primarily for producing oil seals and packaging related ...

    As such they have been banned in many countries, leading to the development of phosphorus-free agents, such as polycarboxylates (EDTA, NTA), citrates (trisodium citrate), silicates (sodium silicate), gluconic acid and polyacrylic acid; or ion exchange agents like zeolites. Alkali builders may also enhance performance by changing the pH of the wash.

  8. Polycarboxylates - Wikipedia

    en.wikipedia.org/wiki/Polycarboxylates

    Polycarboxylates are organic compounds with several carboxylic acid groups. Butane-1,2,3,4-tetracarboxylate is one example. Often, polycarboxylate refers to linear polymers with a high molecular mass (M r ≤ 100 000) and with many carboxylate groups. They are polymers of acrylic acid or copolymers of acrylic acid and maleic acid.

  9. Polyelectrolyte - Wikipedia

    en.wikipedia.org/wiki/Polyelectrolyte

    In polymer terminology, a polyacid is a polyelectrolyte composed of macromolecules containing acid groups on a substantial fraction of the constitutional units. Most commonly, the acid groups are –COOH, –SO 3 H, or –PO 3 H 2. [11]
