In this research the analysis of Butadiene Rubber (BR) addition to mechanical properties of Low Density Polyethylene (LDPE) and Polyvinyl Chloride (PVC) polyblend have been done. Samples were made by blending method using the labo plastomill at temperature of 170 °C and mixing speed 30 rpm. Compositions of the LDPE are 10%, 30%, 50% and 70% weight fraction respectively. Polyblend having PVC content of 30% and 50% added with 5%, 10%, 15% and 20% BR as phase dispersion. The effect of BR addition to microstructure and mechanical properties of polyblend have been thoroughly study. The result show that BR as phase dispersion could not increase mechanical properties, because BR did not improve surface tension of both polymers. This result could be seen from its microstructure which become smoother after BR addition, but yield strength and tensile strength tend to decrease. BR addition could only increase elongation at break of the polyblend.Keywords: LDPE, PVC, Butadiene rubber, Polyblend, Mechanical properties.
