a
Conditions: 30 °C, 24h, HEBiB as initiator, isopropanol as solvent.
b
Calculated from Dp=[M]o/[I]o.
c
Determined by 1H NMR analysis
d
Mn,th=[M]0/[I]0×% Conv.×Mw(monomer) + Mw(initiator). % Conversions were calculated from 1H NMR spectra and 100% conversion was obtained for all polymerizations at 24h.
e
Determined by 1H NMR analysis.
f
Determined by GPC using THF with 0.05 wt % butylated hydroxyl toluene (BHT) and 2 % triethylamine (TEA) as eluent with PMMA standard.
