Solvent molecular weight
WebAt the same time, for polymer solutions with DMAc solvent, the value of dynamic viscosity is less than with NMP, by a factor of 1.09–1.57, depending on the molecular weight of PSF. … 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.
