Description

Viscometry or viscosity method was one of the first methods used for determining the MW of polymers. In this method, the viscosity of polymer solution is measured, and the simplest method used is capillary viscometry by using the Ubbelohde U-tube viscometer. In this method, both the flow time of the polymer solution (t) and the flow time of the pure solvent (t0) are recorded. The ratio of the polymer solution flow time (t) to the flow time of pure solvent (t0) is equal to the ratio of their viscosities (η/η0) only if they have the same densities.
