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.
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.
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]
Povidone-iodine is a chemical complex of the polymer povidone (polyvinylpyrrolidone, PVP) and triiodide (I − 3). [24] It is synthesized by mixing the PVP polymer with iodine (I 2), allowing the two to react. [25] It is soluble in cold and mild-warm water, ethyl alcohol, isopropyl alcohol, polyethylene glycol, and glycerol.
This was a major supplier to the Canadian Expeditionary Force during World War I, which led to the building of a new factory in the newly christened Nobel, Ontario in 1914. CXL also operated another plant across the highway on behalf of British Cordite Limited. All of the Nobel plants closed after the war in 1922, when secondary markets were ...
Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde.

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.
