What is A general intrinsic viscosity-molecular weight relationship for linear polydisperse polymers—3. Applicability to the evaluation of the mark-houwink-sakurada k and a constants about?

Al~tract--An empirical equation relating the intrinsic viscosity of a polymer and its number-, weight-and z-average molecular weights has been used to evaluate the K and a constants of the Mark-Houwink-Sakurada relationship, in cases where data either from monodisperse samples or from samples with known molecular weight distribution are not available. It is shown that accurate K and a values are obtained, provided the ratio of z-to weight-average molecular weights is not too high.
