Reactions performed at room temperature in DCM, with 24 W 450 nm LED irradiation. The following molecular equivalents were used: 2000:20:1 (monomer/CTA/catalyst). All experiments were run to full conversion (15 min in flow, 8 h in batch), and the properties were obtained from calibration with polystyrene standards. Mn = kg/mol.
