    • For this macromolecular application, it should be noted that since the concentration of chain-ends in polymer samples is generally low, the reacting alkoxyamines or RAFT agents could be used in large excess to optimize the functionalization yield without any prohibitive added cost
    • For this macromolecular application, it should be noted that since the concentration of chain-ends in polymer samples is generally low, the reacting alkoxyamines or RAFT agents could be used in large excess to optimize the functionalization yield without any prohibitive added cost. In addition, this excess can also be recovered and "recycled" after isolation of the polymer.

    • 1H NMR could not be used for the quantification of the dithiobenzoate chain-ends and thus for the determination a number average MW since the peaks corresponding to the dithiobenzoate chain-ends overlapped the broad peaks of PS (7-8 ppm).

    • 34 to (i) irreversibly terminated chains via combination, (ii) intermediate radicals, or (iii) irreversible termination products of IR - did appear on the UV chromatograms of the starting PS-DB. It means that at least part of these chains contains a chromophore absorbing at λ-304 nm, unlike terminated PS chains. In addition, it seemed that the former lost their chromophore upon reaction with MAMA - SGI.
