Fracture behavior at low strain rate of dynamically and statically vulcanized polypropylene/styrene–butadiene–styrene block copolymer blends

In this study, the fracture behavior of vulcanized thermoplastic/elastomer (PP/SBS) blends by means of the essential work of fracture (EWF) approach was investigated. Special reference was made to the influence of the blend ratio and the vulcanization method (dynamic and static). Tensile tests showe...
