Abstract A series of ABS/ZnO nanocomposites with different nanoparticles content were synthesized by mass‐mass and mass‐suspension processes. Because nanocomposites obtained through mass‐suspension process had a greater impact resistance than those derived from mass‐mass process, they were subjected to twin‐screw extrusion. The extrusion led to a dramatic morphological change and increase in impact resistance, higher than 100% in most of the cases. On the other hand, the higher the ZnO content, the higher the UV blocking (>95% for 1 and 3% of ZnO) for both materials, before and after extrusion.
