Abstract

The objective of this work was to study the impact properties of Polypropylene /Styrene-Butadiene-Styrene Block Copolymer (PP/SBS) Blends. Concentrations of SBS were 15, 30 and 40 %wt. Special reference was made to the influence of the blend ratio and the vulcanization method (dynamic and static). Impact measurements exhibited that pure PP has extremely low impact strength. Improved impact strength can be achieved by blending PP with SBS via dynamic vulcanization. However, static vulcanization proved to be not as efficient as dynamic vulcanization for improving impact resistance. SEM analysis corroborates these results.
