It is also used in the wine industry as a fining agent for white wine and some beers. In in-vitro fertilisation laboratories, polyvinylpyrrolidone is used to slow down spermatozoa in order to capture them for e.g. ICSI. In molecular biology, PVP can be used as a blocking agent during Southern blot analysis as a component of Denhardt's buffer ...
Polyvinylpolypyrrolidone (polyvinyl polypyrrolidone, PVPP, crospovidone, crospolividone, or E1202) is a highly cross-linked modification of polyvinylpyrrolidone (PVP). The cross-linked form of PVP is used as a disintegrant (see also excipients ) in pharmaceutical tablets. [ 1 ]
It is produced industrially by vinylation of 2-pyrrolidone, i.e. the base-catalyzed reaction with acetylene. [2] It is the precursor to polyvinylpyrrolidone (PVP), an important synthetic material. The NVP monomer is commonly used as a reactive diluent in ultraviolet and electron-beam curable polymers applied as inks, coatings or adhesives. [2]

PVDF is commonly used as insulation on electrical wires, because of its combination of flexibility, low weight, low thermal conductivity, high chemical corrosion resistance, and heat resistance. Most of the narrow 30-gauge wire used in wire wrap circuit assembly and printed circuit board rework is PVDF-insulated. In this use the wire is ...
2-Pyrrolidone itself is used in inkjet cartridges. [5] A variety of pharmaceutical drugs are 2-pyrrolidone derivatives, including cotinine, doxapram, povidone, and ethosuximide, and the racetams. The chemical is an intermediate in the production of the polyvinylpyrrolidone precursor vinylpyrrolidone. [3]
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.
