Summary

The rheological characteristics of cellulose vinyl sulfonate solutions in dilute sodium alkali have been investigated by the method of designed experiment.

It has been established that the flow curves can be described by the equationτ = τ 0 + k × γn.

Regression equations elucidating the effect of temperature and the concentrations of NaOH and cellulose vinyl sulfonate on the coefficientsτ 0, k andn have been derived.

Zusammenfassung

Das rheologische Verhalten von Zellulose-Vinylsulfonat-Lösungen in verdünnter Natronlauge wird mit Methoden der statistischen Versuchsplanung untersucht.

Es wird gefunden, daß die Fließkurven durch die Gleichungτ = τ 0 + k × γn beschrieben werden können.

Regressionsgleichungen, die den Einfluß der Temperatur sowie der Konzentration von NaOH und Zellulose-Vinylsulfonat auf die Koeffizientenτ 0, k undn verdeutlichen, werden abgeleitet.
