polyvinyl pyrrolidone (PVP) is a non-ionic polymer compound. Has developed into non-ionic, cationic, anion 3 categories, industrial grade, pharmaceutical grade, food grade 3 specifications, relative molecular mass from thousands to more than one million homopolymer, copolymer and crosslinked polymer series products, and with its excellent unique properties have been widely used. ​PVP is divided into four stages according to its average molecular weight size, which is usually expressed by the K value, and different K values represent the corresponding average molecular weight range of PVP. The K value is actually an eigenvalue related to the relative viscosity of PVP aqueous solution, and the viscosity is a physical quantity related to the molecular weight of polymers, so the average molecular weight of PVP can be characterized by K value. Generally, the greater the K value, the greater the viscosity and the stronger the adhesion.​pvp Application:​​​As a synthetic water-soluble polymer compound, PVP…

pvp is polyvinylpyrrolidone. Polyvinylpyrrolidone (PVP) is a kind of non-ionic polymer compound. PVP is made from vinyl pyrrolidone (NVP) by bulk polymerization and solution polymerization. In the process of bulk polymerization, due to the viscosity of the reaction system, the polymer is not easy to diffuse, and the polymerization heat is not easy to remove, resulting in local overheating.Therefore, the obtained product has low molecular weight, high content of residual monomer, and is mostly yellow, and has no great practical value. Solution polymerization is generally used to synthesize PVP in industry.​There are two main routes for the production of PVP polymerization, the first is the solution polymerization of N-2-pyrrolidone (NVP) in organic solvents, followed by steam stripping. The second route is aqueous polymerization of NVP monomer with water-soluble cation, anionic or non-ionic monomer.​A crosslinked homopolymer of pure vinylpyrrolidone. Polyvinylpyrrolidone (PVP) has the ability to bind to a variety of substances,…

Crosslinked polyethylpyrrolidone (PVPP) is a kind of crosslinked polymer which is polymerized from vinylpyrrolidone monomer under certain conditions and is insoluble in water, strong acid, strong base and common organic solvents. As an important polymer fine chemical product,PVPP has many excellent and unique properties, and has been widely used in cosmetics, food, medicine and other fields. Characteristics Crosslinked polyvinylpyrrolidone (PVPP) can be seen as a linear PVP molecular chain by physical or chemical crosslinking. Some properties of PVPP obtained by different synthesis methods are different due to different crosslinking methods and crosslinking degrees. Depending on the degree of crosslinking, PVPP appears as super absorbent resins (low crosslinking), water absorbent gels (medium crosslinking) and insoluble substances (high crosslinking). General properties and solubilityCrosslinked polyvinylpyrrolidone PVPP, white or nearly white, with hygroscopicity and easy to flow powder, odorless or slightly odorless, insoluble in water, alkali, acid and common organic solvents, with strong expansion…
