Abstract

This work is devoted to identifying the patterns of influence of the vulcanization accelerator N-cyclohexyl-benzothiazyl-sulfenamide (CBS) on the technological, physico-mechanical, and thermo-physical properties of vulcanizates based on styrene-butadiene rubber. It was found that a decrease in the content of the vulcanization accelerator decreases the maximum torque, and a noticeably longer time is required for optimum vulcanization in the absence of CBS. The thermal conductivity in vulcanizates increases with a decrease in the accelerator concentration due to changes in the structure and molecular mobility of kinetic units. Physico-mechanical indicators increase with a decrease in the concentration of CBS, this is due to a decrease in the apparent density of porous rubbers
