a

Polymerizations performed using 0.5 mmol of monomer, DBMM as the initiator, 0.5 mL of anhydrous EtOAc, and irradiated by 1.6 W white LED at 28 °C.

b

Measured by crude 1H NMR. SL = l/(l + c).

c

Measured by GPC.

d

Initiator efficiency (I*) = Mn,theo/Mn,measured × 100%, where Mn,theo = MW(initiator) + MW(monomer) × conversion × ([monomer]/[initiator]).

e

PhCl was used as the solvent.

f

1,2-Dichloroethane (DCE) was used as the solvent.
