A hybrid nanosilica-polymer material with the surface adaptable to hydrophilic/hydrophobic environment was obtained by modification of parent nanosilica by attachment of 3-glycidoxypropyltri-mcthoxysilane with subsequent grafting of hydrophobic and hydrophilic polymers. First, living PEO was "grafted onto" the modified nanoparticles in reaction with oxiranc rings of the 3-glycidoxypropyl moieties. Then L-lactidc was "grafted from" the surface by ring opening polymerization. Modified nanosilicas were used as fillers of poly(L-lactide-co-glycolide). Influence of nature and content of fillers on mechanical properties of composites were investigated.
