ABSTRACT
The structure of the cationic polymer ZETAG 9014® under the influence of changes in pH of the medium was studied in an aqueous solution. Cationic polymer type ZETAG 9014® is structured under the influence of pH changes. When reducing the pH of the medium, there is a clear trend, in which the average particle size reduces and the size distribution narrows. Conversely, at higher pH values (alkaline region), the average particle diameter broadens the PSD. It is important to note that the type of pH
modifying agent (in particular, acid) can also affect the polymer structuring process. The chemical agents used to modify the pH of the suspension (medium and polymer) were sodium hydroxide (NaOH), potassium hydroxide (KOH), hydrated lime (Ca(OH)) and ammonium hydroxide NH 4 OH).
