摘要：
The curing and mechanical properties of nitrile (NBR) and natural rubber (NR) blends were carried out. Two series of blends were prepared, i.e., NBR/SMR L and NBR/ENR 50 blends. Blends were prepared using a Brabender at a temperature of 60degreesC. Results indicate that the scorch time, t(2) and cure time, t(90) increase with increasing NBR content in both blends, In NBR/ENR 50 blends the increasing content of NBR increases the maximum elastic torque, torque difference, tan delta @, MH and viscous torque. However, in NBR/SMR L blends the opposite trend is observed for maximum elastic torque and torque difference. In both blends modulus at 100% elongation (M100) and at 300% elongation (M300) increases with increasing NBR content, whereas tensile strength and elongation at break show a decreasing trend.
