摘要	First, a sufficient amount of peroxides as initiating moieties were introduced onto the silica gel surface. Subsequently, the Methyl methacrylate polymerization mediated by reverse atom transfer radical polymerization was carried out using CuCl2·2H2O as catalyst and 2, 2′-bipyridine as ligand. By using this hybrid composites as macroinitiatior, atom transfer radical polymerization of acrylamide was realized and functional amphiphilic block copolymers of silicon gel-PMMA-b-PAM with controlled structure were synthesized. The materials were characterized and investigated by XPS, GPC, SPM and TG. The results show that the reaction system is a 'living' polymerization.
