| Abstract: | Ultrafine metal particles immobilized on fine copolymer particles were produced by reduction of copolymer particles–metal ion complexes. Submicrometer-size copolymer particles containing nitrogen, prepared by emulsifier-free emulsion polymerization, were applied. Transmission electron microscopy (TEM) observation and X-ray diffraction analysis indicated that ultrafine noble metal particles with diameter below 10 nm were formed and uniformly immobilized on the surface of copolymer particles. © 1995 John Wiley & Sons, Inc. |
