Simultaneous measurements of small angle x-ray scattering, wide angle x-ray scattering, and light scattering during phase transitions in polymers (invited)

Abstract

In order to obtain detailed information on structural changes in polymers during crystallization and melting, it is necessary to perform real-time measurements of the change in small angle x-ray scattering simultaneously with measurements of the change in wide angle x-ray scattering, light scattering and enthalpy (by differential scanning calorimetry). Different experimental setups to perform such experiments are described. Some examples demonstrate the variety of information that may be obtained by means of these setups.
