“…The present result obtained indicates that 13 C NMR method employed in this work is suitable for investigating the interaction among pure C 60 , polyacrylamide and fullerene based poly (acrylamide) samples [22] which show there is a large shift occurs in the peak values of polymeric samples. In our study also the peak values obtained from 13 C analysis, shows that there exist interactions between carbonyl group of polyacrylamide and the π-system of C 60 .…”

A new classification of the different types of fullerene-containing polymers is presented according to their different properties and applications they exhibit in a variety of fields.13 C NMR and Raman studies of a series of polymeric samples of fullerene-grafted poly (acrylamide), which were prepared by systematic variation of concentration of fullerene and acrylamide, are described.13 C NMR spectral analysis of the polymeric samples showed a peak for fullerene at 143 δppm and for poly (acrylamide) between 170 and 180 δppm and Raman spectral analysis of the polymeric samples gave the Raman band for fullerene between 1470 cm −1 and poly (acrylamide) at 2800 cm. The Tg value, obtained from DSC results, showed a high glass transition temperature at 100.94˚C revealing the presence of fullerene in the polymeric matrix. TGA analysis shows that polymer is thermally stable up to 340˚C.

“…Fullerene-containing polymeric materials have novel optical [11][12][13] and electro active properties [14][15][16][17][18] and have been used in organic solar cells [19,20]. Fullerene-based materials are more thermally stable and are better processable [21].…”

The kinetics of polymerization of vinyl acetate (VA) in presence of fullerene (C 60 ) have been studied using triphenylbismuthonium 1,2,3,4-tetraphenylcyclopentadiene ylide as initiator in dioxane at 80 ± 0.1°C under the blanket of nitrogen. The rate of polymerization (R p ) may be represented as5 , indicating non-ideal kinetics for the polymerization. The energy of activation for the polymerization was found to be 46.2 kJ/mol. The synthesized polymer has been characterized by Fourier transform infrared spectroscopy (FT-IR), proton ( 1 H-NMR) and Carbon-13 nuclear magnetic resonance ( 13 C-NMR) spectroscopic analysis. The molecular weight of the polymer, as determined by gelpermeation chromatographic (GPC) analysis, reduced as the C 60 concentration in the polymer increases. C 60 competed with vinyl acetate for free radicals, produced by ylide, and acts as a radical inhibitor. A part of fullerene was also inserted into the final polymer.
