Abstract
A nonconventional energy-dispersive X-ray diffraction method applied to pha se transitions (EDXD-PT) was used to measure polymer crystallization rates. It enables one to follow the kinetics of phase transitions by a direct com parison of diffraction patterns collected during the process and suitably n ormalized with respect to X-ray absorption spectra taken with the same time scan. With this technique, the memory that a polymer retains of its therma l history is investigated by correlating the crystallization rates to the r esidence time in the melt.
