The vulcanization curves of EPDM blends (not showed) are comparable with reference blend. They showed
plateau, what means that arises network is stable. The minimum torque (ML) and maximum torque (MH) values of
the EPDM blends 2 – 8 are markedly lower in comparison with reference blend. This is related to lower stiffness of
the EPDM blends as well as lower viscosity in comparison with the reference EPDM blend. However, all EPDM
blends have similar or comparable values of optimal vulcanization time like as reference blends.
