| Outline of Final Research Achievements |
We have studied the diffusion behavior of aqueous solutions of polymers where the solutions are subjected to a stable temperature gradient. A concentration gradient is developed owing to the temperature gradient that is called the Ludwig-Soret effect or thermodiffusion. The reported experimental data of the Ludwig-Soret effect for aqueous systems are not sufficient so far. Thus, we have tried to publish experimental data for various aqueous polymer systems measured by means of a laser holographic method established by our laboratory. We have intended to contribute to the developments of nonequilibrium thermodynamics and polymer physics due to deeper understandings of molecular mechanisms of the Ludwig-Soret effect.
