      abstract     = {In this work we study the molar mass dependence of the
                      thermodiffusion of polyethylene oxide atdifferent
                      temperatures in water, ethanol and in a water/ethanol
                      mixture $(C_water$ = 0.7) in a molar massrange up to
                      Mw=180000 g/mol. Due to the low solubility of polyethylene
                      oxide oligomers in ethanol themeasurements are limited up to
                      Mw=2200 g/mol. The specific water/ethanol concentration 0.7
                      is chosen,because at this weight fraction the thermal
                      diffusion coefficient, $D_T,$ of water/ethanol vanishes so
                      thatthe system can be treated as a pseudo binary mixtures.
                      The addition of ethanol will degrade the solventquality, so
                      that we expect a change in the interaction energies, which
                      can be calculated using a modelderived by Würger [1]. We
                      also found that with adding ethanol to water, the
                      thermodiffusion behavior ofPEO changes from thermophobic to
                      thermophilic.},
