The authors report varying grafting densities for Co(L1)–Co(L4) in Figure 3D. Could they clarify the methodology used to determine these values? Was the grafting percentage estimated solely from ¹H NMR integration, or were additional quantitative techniques (e.g., elemental analysis, gravimetric analysis, or mass balance calculations) employed for validation?
In Figure 3E, the authors suggest that reducing catalyst concentration minimizes chain scission. To support this claim, statistical analysis of the SEC data (Mw, Mn) should be included, along with error margins or standard deviations in the figure. Were multiple replicates conducted to ensure the reproducibility of these findings? If not, incorporating additional replicates and error bars in Figure 3E would provide stronger evidence for the proposed trend.
