    • The influence of self-initiation and extra-initiation on NMCRP has recently been considered theoretically (Souaille, M.; Fischer, H. Macromolecules 2000, 53, 248-261). That study reaches the conclusion that the activation rate (alkoxyamine dissociation leading to initiation of polymerization) must greatly exceed the sum of the rates of self- and extra-initiation in order to maintain a living, controlled process.

    • A recent study (Marque, S.; Le Mercier, C. L.; Tordo, P.; Fischer, H. Macromolecules 2000, 33, 4403-4410) has indicated that at elevated temperature, 120 °C, the di-tert-butyl nitroxide radical, which is a part of the A-T unimolecular initiator, is unstable and decays into a transient initiating radical, possibly adding to initiation of polymerization. By performing our NM-CRP processes at significantly lower temperatures, we avoid any significant contribution of this effect on our polymerizations.

    • n = 71 400 g/mol (PDI = 1.47) based on UV detection, which means that a significant portion of the original PS chains underwent interpolymer radical coupling with the PnBMA during annealing. This verifies the "living" nature of the original PS sample.
