Figure 1.

Number-average molar mass (M^obs.) as measured by ¹H NMR spectroscopy versus the molar mass defined by the reaction stoichiometry (M^stoich.). The line plotted alongside the data has a slope of one and an intercept of zero. Polydispersity indices as measured by size-exclusion chromatography are shown adjacent to each data-point. In the case of several closely-space data points, the average polydispersity is shown. Detailed polymerization results are shown in Table 1.
