Dispersed state of C$_{60}$ fullerene in some polymers

The character of C$_{60}$ fullerene dispersion and its temperature dependence in various polymer matrices has been studied by UV-Vis spectroscopy and thermodesorption mass spectrometry. It is established that the degree of fullerene aggregation in these composites varies from molecular-dispersed state to largesize clusters. For the polymers studied, the initial dispersed state is most stable with respect to temperature in the case of poly-$\alpha$-methylstyrene.
