Blending of thermodynamically immiscible butadiene–acrylonitrile rubber (NBR) and polysulphide rubber (TM) results in superior performance materials as regards solvent resistance, and shows some unusual relations between the composition and properties of the blends obtained. Improved performance after vulcanization is probably because of better interphase bonding, resulting from NBR–TM co‐crosslinking. Occurrence of such bonding and its role in amelioration of some of the blends’ properties are discussed in this paper. The effect of TM concentration and crosslinking system on vulcanization state and behaviour is studied by application of chemical, mechanical and thermal methods. © 1998 SCI.
