Abstract

The diffusion coefficient D of polystyrene has been measured in a mixed solvent of carbon tetrachloride and methanol for three solvent compositions where the polymer is close to the theta (unperturbed) state; the CCl4 volume fractions ϕ of the solvent were 0.815, 0.8025 and 0.790. The measurements were made as a function of polymer molecular weight M (from 33000 to 106) and polymer concentration (up to 10 mg/ml) using photon-correlation spectroscopy.
