Stereocontrol of Methyl Methacrylate during Photoinduced Nitroxide-Mediated Polymerization in the Presence of Photosensitive Alkoxyamine

Figure 4

Photopolymerization of MMA in the presence of photosensitive alkoxyamine, light intensity = 20 mW/cm², [MMA] = 9.42 mmol, [PE-TEMPO-Q] = (●)  mmol or (○)  mmol. (a) Kinetics plot; (b) plots of molecular weights and distributions versus conversion, the solid line corresponds to theoretical ; (c) GPC traces of the MMA homopolymers at different conversion: Table 1, runs 9, 12, and 15 ([PE-TEMPO-Q] =  mmol).
