<br/><br/> In this thesis three vulcanization systems sulfur rich sulfur poor and without sulfur were used to vulcanize the synthetic rubbers NBR and EPDM . System (1) (2.5 sulfur + 1.0 MBTS + 0.5 MBT) was the best system for the two types of rubber because it creates mono di and poly sulphide crosslinks and consequently the best rheological and physico - mechanical properties
