Inherent viscosity, definition

The inherent viscosity (I/C2) In (77/770). A plot of inherent viscosity versus concentration also extrapolates to [77] in the limit of C2 0. That this is the case is readily seen by combining Eq. (9.12) with the definition of the inherent viscosity and then expanding the logarithm ... 

Give the definitions and formulas for the relative viscosity, specific viscosity, reduced viscosity, inherent viscosity, and intrinsic viscosity. 

To understand polymer structure, polymers are often dissolved in appropriate solvents, allowing molecular weight or degree of polymerization to be determined from dilute solution viscosity. The relative viscosity, is the ratio of solution viscosity to that of the solvent. The specific viscosity, is the ratio of the difference in solution and solvent viscosities divided by the solvent viscosity. These dimensionless quantities are often divided by the mass concentration of the polymer to obtain several additional terms that have units of dilution or volume per unit mass concentration the reduced viscosity, which is ratio of the relative viscosity to the concentration the inherent viscosity, which is the ratio of the natural logarithm of the relative viscosity and the intrinsic viscosity, [77], which is the common limiting value of the reduced (Huggins definition) or inherent (Craemer s definition) viscosity at infinite dilution of the polymer. The intrinsic viscosity is a concentration ratio it has been used to estimate molecular...
