Polyacrylates, due to their applicability, have become highly used materials in the past two centuries. By replenishing materials with nanofillers (while keeping in mind the importance of optimal dispersion of the filler within the matrix and filler/matrix compatibility) the properties of materials can be tailored and nanocomposites of the desired application properties can be obtained. Titanium (IV) oxide is an extremely popular, stable and non-toxic inorganic nanofiller known for its various useful properties. In this work, pure polyarcrylate (PA) emulsion was synthesized, as well as PA/TiO2 emulsions with TiO2 in concentration range from 1 % to 4 % by monomer mass. Emulsions were prepared by in situ emulsion polymerization and by ex situ procedure. Emulsion density, pH value, flow rate, rheological properties and zeta potential were determined. The results show that the addition of TiO2 nanofiller leads to insignificant change in emulsion density, and this change is different for in situ and ex situ systems. Emulsion’s pH is acidic and increases with the addition of TiO2. Investigation of rheological properties implies that all emulsions, regardless of the preparation method, show Newtonian behaviour and are time-independent. The viscosities of all systems with TiO2 are higher compared to pure PA emulsion. As the concentration of TiO2 increases, the viscosity of ex situ prepared systems compared to pure PA emulsion slightly increases. The viscosities of systems obtained by in situ polymerization are higher compared to ex situ systems. Zeta potential measurement indicates a change in the emulsion stability during the measurement. The most stable emulsion is PA/TiO2 emulsion with 1 % TiO2 prepared via in situ polymerization.
