The decomposition kinetics of the fullerene dimers and photo-oligomers was studied at elevated temperature by Raman scattering. The polymeric content decreases exponentially with the thermal treatment time while the decay time constant decreass at higher temperatures. The activation-type behavior is well described by the Arrhenius law that gives the activation energy E_A = (1.71 ± 0.06) eV/molecule for the dimers and E_A = (0.87 ± 0.06) eV/molecule for the C₆₀ photopolymer.

Keywords: fullerene polymers, Raman spectroscopy, decomposition kinetics.
