In the present study, the influence of blend ratio (mass percentage ratio 100/0, 80/20, 60/40, 50/50, 40/60, 80/20, 0/100) on the curing efficiency and mechanical properties has been studied for two kinds of rubber blends, namely butadiene rubber + ethylene propylene diene rubber (BR/EPDM) and butadiene rubber + ethylene propylene diene rubber + chlorinated paraffin (BR/EPDM/CP). The efficiency of proposed compatibilization technique which includes two-roll mill mixing and vulcanization under the press is verified by the improvement of the mechanical properties of the blend vulcanizates. The compatibility of blends was also evaluated in terms of their cure characteristics, rheological and mechanical properties. Rheometric characteristics (ML, MH, tc90, ts1, and CRI) and Mooney viscosity were determined. The cure time tc90 of BR/EPDM/CP rubber blends increases with an increasing of the EPDM content in the polymer blend. The relatively shorter cure time tc90 of BR/EPDM/CP indicates on better co-curing compared to BR/EPDM rubber blends This work was supported by а grant from the Plekhanov Russian University of Economics Please cite this article as: Sukhareva K.V., Mikhailov I.A., Mamin E.A., et al.
