The Schulz-Blaschke Equation

One form of the Schulz-Blaschke equation is stated as the second-order relationship

Therefore, the following empirical equations were developed to extend the linear range and to minimize the error in the extrapolation for the determination of the intrinsic viscosity. According to the Schulz-Blaschke equation, the reduced viscosity tjred can be plotted as a function of the specific viscosity rispi... 

A comparison of a plot of the reduced viscosity as a function of the concentration according to the Huggins and as a function of the specific viscosity according to the Schulz-Blaschke equation is shown in Fig. 4.6. In this case, both plots lead to the same intersection widi the y-axis,but the Schulz-Blaschke plot allows for a linear extrapolation of the data. 

Improvements in data handling have been suggested. Chee has generalized existing dilute solution theories and has formulated simple equations to estimate unperturbed dimensions and thermodynamic parameters. He has also modified the Schulz-Blaschke equation to give = [>/l (1 -l- / where n varies between... 

Finally, the viscosity of the continuous phase depends on the concentration and type of stabilizer that, in turn, affects the PSD [11]. Okaya [83] employed the following Schulz-Blaschke equation to calculate the viscosity of aqueous PVA solutions ... 

Constant of the [q]-M-equation determined with number average molar masses Schulz-Blaschke constant... 

Other sanianpirical equations, sudi as Aose of Kraana-and Schulz and Blaschke, also are used for processing viscosity data. The Kraemer equation (Ref 9) is...
