Abstract

The paper presents the results of the study on the application of the method of polymerization combination of components. The possibility of the addition of oxidized graphite obtained by various oxidation methods into polyamide-6 at the stage of cationic polymerization of caprolactam has been studied. Its thermal expansion has been confirmed under the conditions of polymer synthesis. The effect of oxidized graphite on the formation of the structure of the modified polyamide has been shown. The improvement of the functional properties of polyamide-6 containing oxidized graphite has been proven: the volumetric electrical resistance decreases by more than 3 times, the coefficient of friction decreases by 40%, the coefficient of thermal conductivity increases by 35%.
