Blends of random polystyrene-SBR were prepared first in a co-rotating twin screw extruder and then injected for being used as impact modifiers. Several experiments were realized, changing the chemical composition of SBR. The blends were made with 5% of SBR in a rigid matrix of polystyrene and the SBRs had different compositions. The samples were characterized by different techniques and compared to a sample with 0% SBR content. The tests performed were: a) mechanical: tensile strength, flexion and Izod impact; b) rheological: melt index flow and melt index razor-sharp at 205 °C and c) morphology: studied by scanning electron microscopy (SEM). The results show that the morphology of surfaces and the mechanical and rheological properties of these blends depend on the relation Styrene/Butadiene and on the structure of the SBRs. |
