The inorganic/organic core‐shell type nanocomposite particles of Al(OH) 3 /PSt were synthesized through the emulsion polymerization of styrene (St, shell monomer) with ammonium persulfate (APS, initiator), polyoxyethylene (50) nonyl phenyl ether (NP‐1050, nonionic surfactant), and ammonium (POE) alkyl arylether sulfate (EU‐S133D, anionic surfactant) in the presence of the modified Al(OH) 3 particles. The improved compatibility of Al(OH) 3 surface with St achieved by the modification with 3‐(trimethoxysilyl) propyl methacrylate ( γ ‐MPS) enabled to form a polymer shell around the mineral particles. The structure of nanocomposites prepared from different feed ratio of Al(OH) 3 /St was investigated by scanning (SEM) and transmission (TEM) electron microscopies.
