A study of polymeric products formed by C60 and C70 fullerene ozonation

The polymeric product formed by reacting C 60 or C 70 fullerenes with ozone, called “ozopolymer”, which is insoluble in non-polar solvents but soluble in water and in methanol was studied by electronic, FT–IR, H-NMR and solid state 13 C-NMR spectroscopy as well as by elemental analysis. The structure and formation of the product is discussed in the framework of the experimental results and Criegee's mechanism of ozonation of unsaturated compounds. The thermal behaviour of the C 60 ozopolymer was studied by DSC and simultaneous TGA-DTA.
