Summary

The stability of polyvinyl chloride (PVC) latex and of Ludox HS-40 silica dispersions in the presence of copper(II) sulfate in varying concentrations has been studied over a broad pH range. The results are presented graphically in the form of the stability domains. The initial precipitation boundary for copper hydrous oxides was found to be affected by the presence of either PVC or silica particles but in each case the direction of the shift was different; for the PVC the boundary was moved to a some-what lower pH region whereas silica caused a shift toward higher pH. Entrapment in the copper hydrous oxide precipitate was found to be a major factor in the removal of PVC particles from suspension but this was not the case for the silica sols.

Zusammenfassung

Die Stabilität von Polyvinyl-Chlorid-Latex (PVC) und von Ludox HS-Kieselsäure-Dispersionen in der Anwesenheit von Kupfer(II)sulfat wurde als Funktion von pH untersucht. Die Resultate wurden in der Form von CuSO4-pH Stabilitätsdomänen für konstante Konzentrationen von Latex und Kieselsäure graphisch dargestellt. Verschiedene Stabilitätsgebiete konnten unterschieden werden, die entweder durch die Bildung von komplexen Kupferionen oder durch die Fällung von Kupferoxyd beeinflußt wurden. Das Einschließen von Latex-Teilchen in das Netzwerk des gefällten Kupferoxyds wurde als die hauptsächliche Ursache für die Ausfüllung von PVC aus der Suspension gefunden. Das gleiche konnte nicht mit der Kieselsäure beobachtet werden. Es wurde weiterhin festgestellt, daß die Anwesenheit von PVC oder Kieselsäure die pH-Grenze der Kupferoxyd-Fällung beeinflussen kann.
