Vr. Albertini et al., First measurements by the EDXD-PT technique of the effect of the melting time on polymer crystallization kinetics, J MACR S PH, B38(4), 1999, pp. 329-339
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.
