TL;DR: In this article, the surfaces of hydrophilic and hydrophobic TiO2 particles were characterized by X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectrography (FTIR) to gain a better understanding of the adsorption mechanism of OLOA 370 (polybutene-succinimide pentamine) on TiO 2 particles dispersed in styrene monomer prior to miniemulsion encapsulation polymerizations.

TL;DR: In this paper, the dispersion of hydrophilic and hydrophobic titanium dioxide (TiO2) particles in organic media (styrene and cyclohexane) was studied to evaluate the effect of dispersion quality (i.e., size and stability) on the encapsulation efficiencies of subsequent miniemulsion polymerizations.

TL;DR: In this article, the authors measured interfacial tension between the interface between the droplets and the aqueous phase and found that the presence of insufficient or excess stabilizer both reduced the interfacial tensions.

TL;DR: In this article, the application of the miniemulsion polymerization technique to the encapsulation of titanium dioxide (TiO2) inside polystyrene latex particles was investigated, where the most successful encapsulations were only achieved when the TiO2 particles, either hydrophilic or hydrophobic, were well dispersed in the styrene monomer prior to formation and polymerization of miniemulsions.

TL;DR: In this paper, a suitable chain extension process was developed, where a hydrophobic chain extender was used to introduce intraparticle cross-linking while maintaining the original small particle size of the nanosize PU/PBMA hybrid latexes.
