**Abstract**
 The effect is investigated of the choice of vulcanising system on the curing parameters and mechanical properties of NBR/EPDM blends. The curing characteristics of the blends were shown to be affected by the accelerator type and the sulphur concentration. Sulphur/benzothiazyl-disulphide and single and binary accelerator systems based on tetramethyl thiuram disulphide were investigated. Higher thermal stability was achieved in blends containing higher levels of sulphur, due, it is thought, to increased crosslinking in the EPDM phase. Results of dynamic mechanical investigations showed differences in Tgs, which increased with increasing the sulphur contents in both vulcanising systems. 27 refs.
