Abstract
Different blends of SBR/NBR compatibilized by butadiene rubber (BR)were prepared according to the well-known standard methods.The modified blend of unfilled SBR/NBR was characterized on the basis of the effect of blend ratio on curing parameters, tensile properties,abrasion resistance, compression set and swelling properties of blends were investigated.It was found that SBR/NBR blends showed comparatively better mechanical properties compared to individual rubber. Curing parameters e.g. low torque (ML) was increased, while a reduction in cure time was observed with increasing SBR ratio in the blend. Results revealed that increasing SBR results in an enhancement of tensile strength (TS)and elongation at break (Eb ).The effect of blend ratio on the swelling and compression set behavior of SBR/NBR compounds was also investigated. from the investigation it was found also that,the increase SBR content inherent with dramatically decline in swelling percentage while the compression set increases with increasing NBR content.Overall, an observed enhancement in curing parameters and mechanical properties has been achieved by studying the effect of blend ratio on the unfilled SBR/NBR blend samples
