Summary

The interaction of polyvinylalcohol (PVA) with valerates of (Sr, Ca, Mg) has been studied by conductivity measurements. The specific conductivity-soap concentration plots showed two transition points in the curves which denote the starting and completion of the interaction. The influence of salt and temperature has been examined. The salt concentration shifts the first transition point to slightly higher concentration where as the second diminishes. Temperature was found not to effect the transition points in polymersoap solutions and even the CMC of soaps were uneffected with temperature.

Zusammenfassung

Die Wechselwirkung zwischen Polyvinylalkohol und Si-, Ca- and Mg-Valeraten wurde konduktometrisch untersucht.

Die Abhängigkeit des spezifischen Leitvermögens von der Konzentration zeigt drei Bereiche unterschiedlicher Neigung. Die beiden Übergangspunkte weisen auf den Beginn und die Beendigung einer besonderen Wechselwirkung hin. Erhöhung der Salzkonzentration verschiebt den 1. Übergangspunkt zu etwas höheren PVA-Konzentrationen, den 2. dagegen zu etwas niedrigeren.
