Structure of povidone-iodine complex, a common antiseptic [3]. There are high-purity injectable grades of PVP available on the market, for specific use in intravenous, intramuscular, and subcutaneous applications.
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]
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 ]

Location of Singapore Singapore is a sovereign island country in maritime Southeast Asia. A global city, it has a highly developed market economy, based historically on extended entrepôt trade and more recently as a financial hub as well. Its economy is known as the most freest, most innovative, most competitive, most dynamic and most business-friendly in the world by various multinational ...
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]
Vinyl polymers are subject of several structural variations, which greatly expands the range of polymers and their applications. With the exception of polyethylene, vinyl polymers can arise from head-to-tail linking of monomers, head-to-head combined with tail-to-tail, or a mixture of those two patterns. Additionally the substituted carbon center in such polymers is stereogenic (a "chiral center")
Poly(4-vinylphenol), also called polyvinylphenol or PVP, is a plastic structurally similar to polystyrene. It is produced from the monomer 4-vinylphenol, which is also referred to as 4-hydroxystyrene. PVP is used in electronics as a dielectric layer in organic transistors in organic TFT LCD displays.
