A study of polymeric products formed by C-60 and C-70 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 C-13-NMR spectroscopy as well as by elemental analysis. The structur e and formation of the product is discussed in the framework of the experim ental results and Criegee's mechanism of ozonation of unsaturated compounds . The thermal behaviour of the C-60 ozopolymer was studied by DSC and simul taneous TGA-DTA. (C) 2000 Elsevier Science Ltd. All rights reserved.
