Conditions are [1000]:[10]:[1] of [BA]:[DBMM]:[PC] with 1.0 eq. DMAc to BA by volume and irradiated by 365 nm LEDs. Batch reactions are conducted under ambient temperatures and flow reactions at 22 ºC.
Determined by 1H NMR.
Measured using GPC.
Calculated by (Conv. × [Mon]/[RX] × Mw,Mon)/1000.
Initiator efficiency (I*) calculated by (Theo. Mn/Calc. Mn) × 100.
