Incorporation of carboxylated nitrile rubber (XNBR) to an immiscible and self-crosslinkable blend of chlorosulphonated polyethylene (CSM) and epoxidized natural rubber (ENR) can result in a miscible ternary rubber blend composition, which is also self-crosslinkable. It was observed by dynamic mechanical analysis that the miscibility in the ternary blend system (containing CSM and ENR in the ratio of 1:1) can be achieved when the XNBR level is higher than 50% of the total composition. XNBR is found to play a dual role: reactive compatibilization as well as plasticization of the system. The self-crosslinking characteristics of the blends were studied by Monsanto rheometry, differential thermal analysis and swelling experiments. Stress-strain properties were also investigated to confirm the homogeneity of the blends
