Unusual thermal diffusion in polymer solutions.
Thermal diffusion forced Rayleigh scattering results on thermal diffusion of poly(ethylene oxide) (PEO) in ethanol/water mixtures are presented. In water-rich solvent mixtures, PEO is found to migrate towards regions of lower temperature. This is typical for polymer solutions and corresponds to a positive Soret coefficient of PEO. In solvent mixtures with low water content, however, the polymer...
متن کاملMolecular-weight dependent thermal diffusion in dilute polymer solutions.
Thermal diffusion of high polymers in a continuous medium is independent of the molecular weight Mw. Accounting for the solvent molecular structure and the Brownian motion of the solute, we derive an additional contribution of opposite sign which is significant for short chains but vanishes as Mw-->infinity. Our findings explain the dependence on Mw observed recently for polystyrene, and its in...
متن کاملDiffusion in Polymer Solids and Solutions
The industrial importance of penetrable and/or impenetrable polymer systems is evident when one faces with a huge number of publications considering various aspects of diffusion phenomenon. Strong worldwide interest to realize more details about the fundamental of the process, generalize the governed laws to new findings, and find fast and reliable techniques of measurement, makes motivation to...
