The Synthesis of polyhedral silsesquioxanes is a very interesting issue for the polymer industry, especially for paint industry; the addition of certain amount of properly substituted polyhedral silsesquioxanes (PSS or POSS) to coating formulation could enhance some properties, like hardness and high contact angles for water. The leader of this project developed a novel process, which incorporates the use of inorganic acidic hydrogen difluorides. The activity of KHF2 was checked in preparation of Ph–T8, Ph–T12, iBu–T8, octa (isooctylsilsesquioxane) (iOc–T8), octa(propylsilses¬quioxane) (Pr–T8) and a few others. This patent will be used as foundation for industrial synthesis in Slovenian companies.

COBISS.SI-ID: 4851482Rheological tests of TSSS paints for solar absorbers, prepared by using different dispersants (POSS 1, POSS 2 and Dysperbyk180) at various PVC ratios, demonstrated the influence of dispersants on the behaviour of paints during deposition. The optimal PVC ratio was obtained by comparing the rheological results to the spectral selectivity of the final coatings.
