Abstract The degree of compatibility of the blend solutions, SBR—NR, SBR—BR, and SBR—NBR, dissolved in toluene was studied using ultrasonic methods. The variation of longitudinal ultrasonic velocity with composition is linear with SBR—NR and SBR—BR blends indicating compatible systems. For SBR—NBR the plots of ultrasonic velocity versus composition deviates from linearity according to the degree of compatibility of this blend system. The behavior was confirmed by heat of mixing calculations as well as ultrasonic attenuation measurements.
