Polyvinylpyrrolidone
MF: CH4
MW: 16.04246
CAS: 9003-39-8
Polyvinylpyrrolidone, abbreviated as PVP, is a non-ionic polymer compound. It is the most characteristic of N-vinylamide polymers and the most extensively studied fine chemical. Has developed into three categories of non-ionic, cationic, anionic, industrial grade, pharmaceutical grade, food grade 3 specifications, relative molecular weight from thousands to more than one million homopolymer, copolymer and cross-linked polymer series products , And has been widely used with its excellent and unique properties.
PVP is divided into four levels according to its average molecular weight. It is usually expressed by K value, and different K values represent the corresponding PVP average molecular weight range. The K value is actually a characteristic value related to the relative viscosity of the PVP aqueous solution, and the viscosity is a physical quantity related to the molecular weight of the polymer, so the K value can be used to characterize the average molecular weight of PVP. Generally, the greater the K value, the greater the viscosity and the stronger the adhesion.

Boiling point: 217.6°C
Melting point: 130°C
Flash point: 93.9°C
Average molecular weight: 8000-700000
Stability: stable under normal temperature and pressure
Solubility: very soluble in water and solvents containing halogenated hydrocarbons, alcohols, amines, nitroalkanes and low molecular fatty acids, etc., insoluble in a few solvents such as ether, turpentine, aliphatic hydrocarbons and alicyclic hydrocarbons. Compatible with most inorganic acid salts and various resins.
Properties: It is a hydrophilic, easy-flowing white or almost white powder with a slight odor.
