Abstract
Diethyldithiocarbamyl-modified silica nanoparticles were prepared and used as macroinitiator for the surface-initiated atom transfer radical polymerization (SI-ATRP) of styrene under UV irradiation. Well-defined polymer chains were grown from the nanoparticle surfaces to yield particles composed of a silica core and a well-defined, densely grafted outer PS layer with a mass ratio of styrene to silica, or percentage grafting, of 276.3% after an UV irradiation time of 5 h.
