Summary

In this work, elongational viscosity data obtained for dilute solutions of Separan NP 20 in glycerol, are presented. The data are taken under transient stress conditions with two different experimental techniques.

For comparison with theory the non-linear elastic dumbbell model has been used both for monodisperse and polydisperse cases. Agreement between data and theory is satisfactory only by taking into account internal viscosity effects.

Zusammenfassung

In dieser Arbeit werden Meßergebnisse an Dehnströmungen mit verdünnten Lösungen von Separan NP 20 in Glyzerin mitgeteilt. Dabei werden zwei verschiedene Meßmethoden mit nicht-konstantem Spannungsverlauf angewandt.

Für Vergleiche mit der Theorie werden als Modelle sowohl monodisperse als auch polydisperse Suspensionen nicht-linear elastischer Hanteln herangezogen. Die Übereinstimmung ist erst dann zufriedenstellend, wenn man zusätzlich den Einfluß einer „inneren Viskosität“ in Rechnung stellt.
