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.
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]
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.
Formvar refers to any of several thermoplastic resins that are polyvinyl formals, which are polymers formed from polyvinyl alcohol and formaldehyde as copolymers with polyvinyl acetate. They are typically used as coatings, adhesives , and molding materials.
4-Vinylpyridine (4-VP) is an organic compound with the formula CH 2 CHC 5 H 4 N. It is a derivative of pyridine with a vinyl group in the 4-position. It is a colorless liquid, although impure samples are often brown.
2-Vinylpyridine is an organic compound with the formula CH 2 CHC 5 H 4 N. It is a derivative of pyridine with a vinyl group in the 2-position, next to the nitrogen. It is a colorless liquid, although samples are often brown.
In enzymology, a polyvinyl-alcohol oxidase (EC 1.1.3.30) is an enzyme that catalyzes the chemical reaction. polyvinyl alcohol + O 2 oxidized polyvinyl alcohol + H 2 O 2. Thus, the two substrates of this enzyme are polyvinyl alcohol and O 2, whereas its two products are oxidized polyvinyl alcohol and H 2 O 2.
