Fikentscher’s value of viscosity characteristics K-value represents a viscosity index relating to molecular weight and is calculated by the following Fikentscher’s formula with relative viscosity which is measured by capillary viscometer at 25ºC
|
K= (1.5 logηrel -1)/ (0.15+0.003c)+ (300c logηrel + (c+1.5clogηrel )2)1/2/ (0.15c+0.003c2)
ηrel : Relative viscosity of aqueous polyvinylpyrrolidone solution to water
c : Content (w/w%)of polyvinylpyrrolidone in aqueous polyvinylpyrrolidone solution |
