Povidone K 90, also commonly called polyvidone or povidone, is a water-soluble polymer made from the monomer N-vinylpyrrolidone.
Povidone K 90 is a non-ionic high molecular polymer.
Povidone K 90 is classified according to its average molecular weight.
Povidone K 90 is customarily used to indicate the K value.
Different K values represent different PVP average molecular weight ranges.
The K value is actually a characteristic value related to the relative viscosity of the PVP aqueous solution, and the viscosity is a physical value related to the molecular weight of the high molecular polymer.
Therefore, the K value can be used to characterize the average molecular weight of PVP.
Generally, the K value is more Large, the greater the viscosity.
