Abstract

The purpose of the work is to substantiate the mechanism of interaction of a mixture of fullerene fractions С50÷92 with the polymer matrix of natural and synthetic rubbers with the subsequent solution of the task of identifying their compliance with specified technological parameters in terms of the content of a nanoscale component. The authors make a study of an industrial brand of synthetic butadiene rubber: SBR-Nd and SBR-Ti, according to synthesize on neodymium and titanic catalysts such as natural rubber grade NR RSS1. As a modifier of the polymer matrix, a mixture of fullerenes of fraction C50-C92 was used in the following ratio: C50-C58 (14.69%), C60 (63.12%), C62-C68 (5.88%), C70 (13.25%), C72-C92 (3.06%). When processing the spectra, we used: autofiltration of the signal by a running spectral window, automatic correction of the baseline, complicated ATR correction for the depth of penetration into the film material. It is revealed that the nature of the interaction of a mixture of fullerenes with rubbers is determined by the uncertainty and chemical nature of the elastomer and does not depend on the nature and activity of the filler. An algorithm is developed for the identification of diene rubbers modified with a mixture of fullerenes. Practical approbation of the algorithm on the example of identification of a mixture of C50-C92 fullerenes in polymer matrices of various chemical nature is carried out based on the IR spectroscopy method. The accuracy of identification was 97-98%.
