A review. Two general microemulsion-based routes towards surface-functionalized metal oxide nanoparticles serving as macro-initiators in "grafting from" atom transfer radical polymn. (ATRP), are presented. Metal alkoxides modified with several β-diketone derivs. carrying potential ATRP-initiating sites served as precursors for the particle formation leading in an sol gel process to in situ-functionalized titanium-, zirconium-, tantalum-, vanadium-, yttrium-, and iron oxide nanoparticles. The obtained systems were compared with metal oxide nanoparticles prepd. by using metal salts as precursors which were functionalized in a second step with ATRP-initiator contg. silane coupling agents. The obtained particles had diams. between 5 nm and 640 nm and served as multifunctional polymn. initiators in ATRP using styrene and Me methacrylate as monomers.
