The composite powders of metal oxides and MMA polymer were prepared by adding H_2SO_3 solution to mixed suspension of MMA monomer, metal oxide :powders and water. Powders of different size and shape were obtained according to the reaction conditions and the natures of oxides. The properties of these powders were studied by microscopic observation, thermal analysis and measurements of corona charging properties. The polymer contents in these powders are found to be affected by the natures of the oxides, reaction temperature and quantity of H_2SO_3 solution. The corona charging properties of composite powders depend on the natures of oxide and reaction conditions, but no clear relation between the polymer content and these charging properties is found. The charging value of Fe_2O_3 composite powder is larger than that of MMA powder and the decay of charge is slow. On the other hand, the charging value of ZnO composite powder shows the medium value and the decay of charge is rapid.
