(a) SEM test samples and the diagram of the test area. (b) A comparison of the micromorphology between the poly(MMA-r-nBA) with different molar ratios before and after the samples are stretched. Here, samples are chosen from the fracture surface. (c) Cross-sectional SEM image of the poly(MMA-r-nBA) with different molar ratios before and after the samples are stretched; and a magnified view of the dimple region is shown.
