Abstract
The temperature and pressure dependence of the Flory-Huggins parameter was determined for several polymer blends from the SANS structure fac tor S(Q --> 0) for pressures less than or equal to 1.2 kbar. It can be split into an enthalpic and an entropic part. Furthermore, the radius of gyration was investigated with S(Q) as a function of pressure.
