Current Analysis of Huggins and Kraemer Plots for Determining the Intrinsic Viscosity of Macromolecules and the Corresponding Dimensionless Parameters
G. M. Pavlov, A. A. Gosteva
Abstract
Abstract The Huggins and Kraemer plots are compared to estimate the intrinsic viscosity of macromolecules belonging to different classes of macromolecular compounds. It is shown that the Kraemer plot is linear in a larger range of concentrations suitable for extrapolation to zero concentration. A change in the sign of the Kraemer parameter makes it possible to detect the prevalence of polymer–polymer interactions over volume effects more clearly than an increase in the Huggins parameter.
