Monodisperse Polystyrene and its copolymer beads containing amine function were prepared for the electroless silver plating using reduction of silver alkylcarbamate complex in organic solvent. soap-free emulsion polymerization was adopted for the polymerization of styrene, divinylbenzene (DVB), and 2-(NN-dimethylamino) ethyl methacrylate (DAEMA) in the presence of poly(vinyl alcohol) in a water/methanol solvent. The resulting poly (styrene/DVB/DAEMA), containing 30/0 similar to 1.5/0 similar to 3 wt% in monomer composition, were found to be a sphere-type particle with diameter of 1 mu m. Silver Ag-coated polystyrene beads were prepared by in sito reduction of a silver 2-ethylhexylcarbamate (Ag-EHCB) complex solution with hydrazine without pretreatment of polystyrene beads. Robust Ag/polystyrene beads were analyzed by SEM, UV-visible spectrometer and XRD.
