Due to the wide use of the EDOS plasticizer, which has increased volatility, in technology of preparing polyvinyl chloride materials for machine engineering, its interaction with thermally treated rice husk has been studied to assess possibility of EDOS sorption on its surface to reduce plasticizer migration. Infrared spectroscopy studies confirmed partial adsorption of EDOS plasticizer on the surface of thermally treated rice husk (TRH) due to hydrogen bonds formation between this filler and the plasticizer, which allows to enhance water resistance of plasticized polyvinyl chloride compositions due to the lower leaching of EDOS when exposed to distilled water.
