Zusammenfassung

Es wurde die Morphologie von PET-Proben untersucht, die infolge von längeren thermischen Behandlungen eine hohe Kristallinität aufwiesen.

Die Ausgangsstoffe bestanden aus Filamenten, die vorher unterhalb derTg-Temperatur oder unter praxisnahen Bedingungen verstreckt und dadurch orientiert worden waren.

Für die Charakterisierung wurden Kleinwinkel- und Weitwinkeldiffraktionsverfahren sowie das Verfahren der umgekehrten Gas-Chromatographie bei konstanter Temperatur angewendet.

Summary

Morphological characterization of highly cristalline PET has been carried out. Yarns were previously orientated by drawing under theTg or by industrial drawing, after that they were thoroughly annealed at a constant length. For the morphological characterization of the samples, X-ray diffractometric techniques, both high and low angle, and isothermal reverse gas-chromatography were used.
