a),b) Pseudo first-order kinetics of polymerisations with [DMA]/[RAFT]/[ZnTPP] = 200:1:0.01 at 1m DMA in a a) 96-well plate and b) an NIR cuvette, with and without removal of oxygen prior to polymerisation. MacroR1 = DP 15 DMA macroRAFT agent prepared from R1 and purified prior to chain extension. Arrows indicate the bubbling of air through the cuvette with a pipette after measurement. c),d) GPC molecular weight distributions from the chain extension experiment and final kinetic samples (c) as well as from five other acrylamides at full conversion (d).
