Polyvinylpyrrolidone (PVP) is characterized by its K value, a dimensionless value which is a function of the average molecular weight, the degree of polymerization, and the intrinsic viscosity. It is calculated from dilute solution viscosity measurements. log (Ns/No)/C = (75 Ko x Ko)/(1 + 1.5 Ko C) + Ko where Ns = viscosity of the solution, No = viscosity of the solvent and C = concentration in grams per 100 ml of solution. K = 1000 x Ko. The larger the K value for a material, the higher the viscosity.
This compound is readily soluble in water. It has also been reported in the chemicals encyclopedia published by the Royal Society of Chemistry, 12th ed., Entry# 7879 to be soluble in ethanol and chloroform, but practically insoluble in ether.
