| Abstract: | A possibility of preparation of monodisperse magnetic polymer particles containing carboxylic groups by the methid of emulsion (co)polymerization in the presence of a magnetic liquidis considered. Angulation of the magnetite nanoparticles by polymeric spheres of styrene-acroleine copolymer followed by incapsulation to the polystyrene coat is studied. Monodisperse particles with inclusion of the magnetite nanoparticles 30 nm to 1 μm size containing up to 5.6 μmol g?1 surface carboxylic groups are obtained, their electrosurface and magnetic properties are studied. |
