Fig. 17: A set of small-angle X-ray scattering curves (SAXS) taken after a pressure jump from 350 bar to 650 bar at a temperature of 140°C. The material was initially in the disordered state and a phase separation to the hexagonal phase occurred. The diffraction patterns are taken with a time interval of initially 10 seconds and later 1 minute per spectrum. The morphology peak narrows with time and a second order peak appears, characteristic of the hexagonal structure.
