  2. 2-Pyrrolidone - Wikipedia

    en.wikipedia.org/wiki/2-Pyrrolidone

    2-Pyrrolidone is produced industrially almost exclusively by treating aqueous gamma-butyrolactone with ammonia at a temperature of 250–290 °C and pressures ranging from 0.4–1.4 MPa over solid magnesium silicate catalysts. [3] The reaction is carried out in a tubular reactor which is packed with the solid catalyst. The latter is arranged as ...

  3. N-Vinylpyrrolidone - Wikipedia

    en.wikipedia.org/wiki/N-Vinylpyrrolidone

    N-Vinylpyrrolidone (NVP) is an organic compound consisting of a 5-membered lactam ring linked to a (2 carbon) vinyl group. It is a colorless liquid although commercial samples can appear yellowish. It is produced industrially by vinylation of 2-pyrrolidone, i.e. the base-catalyzed reaction with acetylene. [2]

  4. Polyvinylpyrrolidone - Wikipedia

    en.wikipedia.org/wiki/Polyvinylpyrrolidone

    Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.

  5. Pyrrolidine - Wikipedia

  6. Vinyl group - Wikipedia

    en.wikipedia.org/wiki/Vinyl_group

    In organic chemistry, a vinyl group (abbr. Vi; [1] IUPAC name: ethenyl group [2]) is a functional group with the formula −CH=CH 2. It is the ethylene (IUPAC name: ethene) molecule (H 2 C=CH 2) with one fewer hydrogen atom. The name is also used for any compound containing that group, namely R−CH=CH 2 where R is any other group of atoms.

  7. 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]
