It has been known that the plot of the reduced viscosity of high polymer solutions against their concentration gives minima at certain concentration, C. Taking [η] <SUB>c</SUB>, as the reduced viscosity at the concentration, Cc, the numerical values of [η] <SUB>c</SUB>·C<SUB>c</SUB> fall into two classes with respect to the kind of the solution. In the first class, [η] <SUB>c</SUB>·C<SUB>c</SUB>, gives the value 2.5 and in the second class, it gives 0.1 approximately. Assuming that the polymer molecules can take spherical or rod-like configuration in the solution and that they can just contact with each other at the critical concentration, C<SUB>c</SUB>, the results mentioned above can be derived theoretically.
