a
TBPB is t-butyl peroxybenzoate.
b
Dilution with 50 wt% solvent.
c
Monomer conversion obtained with 1H NMR.
d
PMMA-calibrated THF-GPC values.
e
F PhDL value determined by the 1H NMR analysis of the purified polymer. In the parenthesis, FPhDL value calculated from the monomer conversion (monomer consumption) determined using 1H NMR is given.
