| Abstract: | The C 60 chemically modified PMMAs with different C 60 contents were synthesized through one step method of sodium naphthalene initiated anionic polymerization reactions. The influence of differnet C 60 contents upon the properties of these polymers were studied with FT IR, UV visible, TGA and GPC. 13 C nuclear magnetic resonance(NMR) results provided strong evidence for the covalent attachment of poly(methyl methacrylate) units to the C 60 cores. The C 60 chemically modified PMMAs were also synthesized with several step method to have a preliminary study on the reaction mechanism. |
