✦ Synopsis

Blending of thermodynamically immiscible butadieneÈacrylonitrile 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 NBRÈTM co-crosslinking. Occurrence of such bonding and its role in amelioration of some of the blendsÏ properties are discussed in this paper. The e †ect of TM concentration and crosslinking system on vulcanization state and behaviour is studied by application of chemical, mechanical and thermal methods.
