The effects of PC-oligomer addition on the internal morphology and mechanical properties of injection mouldings of polycarbonate (PC)/Acrylonitrilebutadiene-styrene (ABS) blends were investigated. Incorporating PC-oligomer into PC/ABS blends caused a significant improvement in strain at break under tensile loading without sacrificing tensile modulus and strength. Highly elongated ABS phases along the flow direction were observed in the blend with PC-oligomer.
