Fig. 4. HEAA initiated eROP of CL (I : M 1 : 20) was monitored by both 1H-NMR analysis and GPC. Left: molecular mass (Mn) determined by GPC and 1H-NMR spectroscopy plotted against conversion. Right: GPC chromatograms obtained during the experiment. Reactions were performed at a monomer concentration of 0.143 g mL−1.
