Summary
X-ray diffraction and dynamic mechanical studies have been made on a series of undrawn, heat-crystallized poly(ethylene terephthalate) fibers. An expression has been developed to relate the position of the α dispersion peak to crystallinity and crystal size parameters. This expression gives good agreement with experiment. Consideration is also given to the effect of drawing on the position of the α dispersion.
Zusammenfassung
Untersuchungen über die Röntgenbeugung und die dynamisch-mechanischen Eigenschaften einer Reihe unverstreckter, kristalliner Polyäthylenterephthalat-Fasern wurden angestellt. Eine Beziehung zwischen α-Dispersion und Kristallinität sowie Kristallgröße wurde aufgestellt. Gute Übereinstimmung zwischen der aufgestellten Beziehung und den experimentellen Daten wurde gefunden. Die Lage der α-Dispersion in Beziehung zum Grade der Verstreckung wurde untersucht.
