^a Polymerizations were carried out in DMSO solvent (BL concentration was 1mol/L) at room temperature up to 100% conversion of monomer; ^b Polymerization time: entries 1–5: 2 days, entries 6–10: 14 days and entries 11–12: 5 days; ^c Monomer concentration—8 mol/L; ^d Calculated form equation: M_nth = [M]₀ × 86/[I]₀ where [M]₀ and [I]₀—monomer and initiator concentration, 86—molar mass of BL; ^e Estimated form ¹H NMR from equation: M_nNMR = (I_polymCH × 86)/(I_PhOCH-+ I_HOCH + I_=CH).
