The toughening effect of the content of a core‐shell poly(butyl acrylate)/poly(methyl methacrylate) latex polymer (PBA‐ cs ‐PMMA) on the mechanical properties, morphology and compatibility of its blends with polycarbonate(PC), i.e., PC/PBA‐ cs ‐PMMA, was studied. The mechanical properties of the blends are strongly affected by varying the content of PBA‐ cs ‐PMMA in the blend. When the PBA‐ cs ‐PMMA content is only 5 wt.‐%, the impact strength of PC/PBA‐ cs ‐PMMA is almost 19 times as high as that of pure PC, indicating that PBA‐ cs ‐PMMA is a very good impact modifier for PC. With increasing interphacial layer thickness and decreasing interphacial tension, the interphacial activity becomes more and more effective and, at the same time, miscibility increases too.
