Abstract: Tetraacryloxyethoxysilane syntheslied by the reaction of 2-hydroxyethyl acrylatewith silicon tetrachloride was used in preparation of the transparent poly (2-hydroxyethylacrylate)/silicon dioxide composites by sol-gel method.The composition of the compositeswere analyzed by electronic energy spectroscopy, elemental analysis and thermogravimetry.The composites have transparency greater than 80%, with thermal stability being increasedwith the silicon dioxide content.

Key words: poly(hydroxyethyl arylate), silicon dioxide, composite, sol-gel method
