Abstract
The construction of a generalized concentration dependence of the viscosity η of concentrated solutions is analyzed. It is shown that there should be a single dependence for different polymers in different solvents of the form: (η/ηo)1−2k=1+(1−2k)c[η], where k is the Huggins-Martin constant, and [η] is the intrinsic viscosity. Deviations from this relation may be observed in the presence of structure formation in the solution or when the experimental temperature is close to the glass-transition temperature of the system.
