Webb23 sep. 2013 · FIG. 1. You cannot measure viscosity at a shear rate of zero because viscosity is a measurement of resistance to flow. In order to measure resistance to flow … WebbDefinition. The intrinsic viscosity as measured from a dilute solution of macromolecules contains information on the macromolecular shape, flexibility, and (for nonspherical particles) molar mass of macromolecules. It is defined as the reduced specific viscosity in the limit of “infinite dilution” or zero concentration.

Webb24 juni 2013 · Flow rate in a polymer is related inversely to viscosity. High-viscosity materials flow with greater resistance and therefore more slowly under any particular set of conditions than low-viscosity materials do. Therefore, higher-MW polymers have lower MFR values and lower-MW polymers have higher MFR.
