Abstract: In this paper, the infinite dilution diffusion coefficients of poly(ethylene glycol) and poly(propylene glycol) In water were measured by using the Taylor dispersion technique. For poly(ethylene glycol), the measurements were performed in the temperature range of 303-318 K at four different polymer molecular weights. The diffusion coefficient was found to increase linearly with temperature but decrease exponentially with molecular weight. In addition, the diffusion coefficient of poly(propylene glycol) (M = 400) was found to be lower than that of poly(ethylene glycol) at the same molecular weight but has the same temperature dependence. © 1991 American Chemical Society.
