Rheological and Electrical Behavior of Styrene - Butadine Rubber ( S B R )

Styrene – Butadiene Rubber ( SBR ) with different concentration has been dissolved in toluene ( 0.1 – 0.6 ) g / ml . The Rheological and Electrical properties were investigated which have shown that the Shear iscosity , relative viscosity , Specific viscosity , and density were affected by increasing their values as the concentration increase , while the opposite behavior was shown in reduced viscosity The capacitance and dielectric constant increase as the percentage of concentration increase .
