Abstract

The self-diffusion coefficients of chloroform in poly(isopropyl acrylate)-chloroform solutions have been studied as a function of concentration and temperature using the pulsed field-gradient spin-echo NMR method. It is found that the self-diffusion coefficients of the solvent can be adequately fit using a simple free volume approach with either a concentration or temperature superposition. It was noted that the free volume parameters derived from the self-diffusion data are the same as those which can be derived from deuterium NMR transverse relaxation time measurements of the polymer in the same systems.
