Es wurde die Morphologie yon PET-Proben untersucht, die infolge yon l~ingeren thermischen Behandlungen eine hohe Kristallinit~it aufwiesen. Die Ausgangsstoffe bestanden aus Filamenten, die vorher unterhalb der Tg-Temperatur oder unter praxisnahen Be- dingungen verstreckt und dadurch orientiert worden waren. Ftir die Charakterisierung wurden Kleinwinkel- und Weitwinkeldiffraktionsverfahren sowie das Verfahren der umgekehrten Gas-Chromatographie bei konstanter Tempe- ratur angewendet,
Morphological characterization of highly cristalline PET has been carried out. Yarns were previously orientated by drawing under the Tg or by industrial drawing, after that they were thoroughly annealed at a constant length. For the morphological characterization of the samples, X-ray dif- fractometric techniques, both high and low angle, and isothermal reverse gas-chromatography were used.

Abstract
Morphological characterization of highly cristalline PET has been carried out. Yarns were previously orientated by drawing under the Tg or by industrial drawing, after that they were thoroughly annealed at a constant length. For the morphological characterization of the samples, X-ray dif- fractometric techniques, both high and low angle, and isothermal reverse gas-chromatography were used.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
