Abstract
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.
