Relationship between Molecular Weight and Viscosity

Viscosity is defined as the property which determines the resistance to motion when a sheering force is exerted on the fluid under laminar flow conditions. [Pg.57]

If T] denotes the dynamic viscosity of a polymer solution of concentration C, and i ois the intrinsic viscosity of the solvent of the same temperature, then  [Pg.57]

The ratio ofis the reduced viscosity or viscosity number. [Pg.57]

The intrinsic viscosity characterises the capacity of the polymer to increase the viscosity of the system when unaffected by the presence of other polymer molecules, that is at zero concentration (when C = zero). [Pg.58]

There is no direct method for obtaining molecular weight from the intrinsic viscosity of a polymer. [Pg.58]
