Bulk photo-CuAAC polymerization kinetics using FTIR. 1 : 1 azide : alkyne mixture with varying exposure times, including 0 minute (closed circle), 0.5 minute (open circle), 1 minute (closed triangle), 2 minutes (open triangle), 3 minutes (closed square), 60 minutes (open square). Azide 2c was polymerized stoichiometrically with alkyne 3 in the presence of 2 mol% CuCl2[PMDETA], 2 mol% CQ per azide functional group, and <1 wt% methanol. Each mixture was irradiated at 35 °C with 75 mW cm−2 of 400–500 nm light following 3 minutes in the dark as a baseline measuring period. Only the start of light irradiation is highlighted in gray dotted line.
