This article examines the rheological properties of a system composed of polyol and colloidal silica. Three types of nanosized silicas with hydrophilic and hydrophobic surfaces were studied: A200 with OH surface groups, R974 with CH 3 surface groups, and R805, which is grafted with a C 8 H 17 alkyl chain. Rheometric measurements showed that the dispersions of R805 silicas have...
