Features of the Thermal Degradation of Reprecipitated Polybutadienes under the Influence of a Mixture of C 50 -C 92 Fullerenes

Abstract

An investigation was made of the mechanism of physicochemical interaction of a mixture of C₅₀-C₉₂ fullerenes with diene rubbers. In view of their similarity, experimental data obtained by IR spectroscopy were processed on the basis of a chemometric approach to describing the results. Very small changes in the optical density of the characteristic groups of the rubbers were analysed. To extract hidden information concerning the chemical interactions of the fullerene mixture with the rubber base from the files of experimental data, discriminant analysis was used. The effect of fullerenes on macromolecules of the investigated rubbers was shown. The groups of rubbers capable of interacting with the introduced modifier were determined. It was established that the interaction of the fullerene mixture with the rubber proceeds by unconjugated double bonds.
