Initiation of surface graft polymerization by ceric ions on polymer microspheres
The surface graft polymerization of acrylamide on poly(styrene-co-acrylonitrile) copolymer microspheres by the initiation of ceric ions was studied. The grafting was verified by IR spectra and X-ray photoelectron spectroscopy measurements. The resultant microspheres with surface-grafted polymer chains were employed in the preparation of polymer-microsphere-supported palladium composite particles. The composite particles were then studied by transmission electron microscopy and X-ray diffraction. (C) 2003 Wiley Periodicals, Inc.
