Viscosimetric Determination of the Molar Mass

Abstract

The intrinsic viscosity [η] of a polymer in a certain solvent can be correlated with the molar mass M:

$$ [\eta ] = {K_{[\eta ]}} \cdot {M^a} $$

((6.1))

In the literature, this dependence is referred to as the [η]-M-relationship or the Kuhn-Mark-Houwink-Sakurada-relationship (KMHS-relationship). K[η] and a are constant for a given solvent and temperature.
