Abstract

A new method has been proposed for estimating the parameters K~m~ and a in the Mark‐Houwink equation [η] = K~m~M̄~v~^a^ from the measurements of molecular weight and second virial coefficient for a single polymer sample. Although the treatment has been based upon existing theories, the partly draining effect has been taken into account as well as the excluded volume effect. Only one sample need be used, and thus the usual more laborious method is unnecessary. General applicability of our method has been shown by several examples cited from published data.

In the calculation of molecular weight averages by GPC, the traditional method uses the calibration curve obtained at the same concentration as the samples, which results in a large degree of disagreement between molecular weight averages at several concentrations. Because of the concentration depen
