WebDetermine the intrinsic viscosity, [] c, by interpolation, using the Intrinsic Viscosity Table in the Reference Tables section. Calculate the degree of polymerization, P, by the … In size-exclusion chromatography, such as gel permeation chromatography, the intrinsic viscosity of a polymer is directly related to the elution volume of the polymer. Therefore, by running several monodisperse samples of polymer in a gel permeation chromatograph (GPC), the values of and can be determined graphically using a line of best fit. Then the molecular weight and intrinsic viscosity relationship is defined.
