## Abstract The weightβaverage molecular weight is estimated by an extrapolation technique based on a linear relation between the viscosityβaverage molecular weight __M__~__v__~ and a MarkβHouwinkβSakurada constant. This method may also be used to assess the unperturbed dimensions of polymers. If t

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
## Abstract An empirical method for absolute molecular weight determination of polymers from viscosity measurements is described. The essential assumptions of the method are: (__a__) the Huggins' slope constant for any flexible polymer has a maximum value of 0.5 at the precipitation point; (__b__)
