This work is devoted to study of halide mechanochemical modification of nitrile-butadiene rubber (BNCS-18AN) with a chlorine-containing reagent. In previous studies, the optimal parameters for modification were established. The modification was carried out in a laboratory rubber mixer. The obtained halogen-containing rubbers were investigated using ESR spectroscopy. Rubber compounds based on obtained chlorinated butadiene-nitrile rubbers (CNBR), were prepared and their tensile stress-strain properties and curing characteristics were investigated. Vulcanization of rubber compounds was carried out under the established optimal conditions. Physical and mechanical properties of the rubbers were determined. Subsequent studies showed the most probable regularities of the mechanochemical halide modification of nitrile butadiene rubber (BNCS-18AN) with a chlorine-containing modifier (CHCl) in a rubber mixer.
