Solvent Self-diffusion in Semi-dilute and Concentrated Polystyrene Solutions
This study examined the self-diffusion coefficients of several solvents in polystyrene solutions. Two regions have been explored. The first is the dilute to semi-dilute region (0-80 wt%) at room temperature and above for a variety of solvents. It is found that the normalized self-diffusion behavior is independent of the polymer-solvent pair and the molecular weight of the polymer. The self-diffusion of cyclohexane, toluene and n-butyl acetate in polystyrene at high temperatures (60-105 degree C) and high solids content (75-95 wt% solids) has also been probed. It is found that the self-diffusion coefficients show Arrhenius behavior with temperature.
