Chemical modification of rubber crosses in the processes of waste automotive tires

The article presents the results of a study of the chemical modification of rubber crumbs in solutions of hexane, petroleum ether, benzene, toluene, as well as bituminous products of extraction recovery of chemically modified hard coals (nitric acid and acetic acid coal extracts). The obtained data allow us to talk about the possibility of using coal extracts as promising modifying materials in technologies for the secondary use of rubber waste.
