Adsorption of linear polymers (poly(vinyl)alcohol (PVA), poly(ethylene)glycol (PEG)) onto surface of fumed oxides was measured by viscosimetric method. According to the IR spectroscopy data, a portion of surface hydroxyls does not interact with polymer molecules at monolayer coverage with PVA while...
