Varying intensity in polymer systems using Irgacure 819 and CuCl2-PMDETA along with monomers 1 and 2 as the reactants using 405 nm wavelength and a sample thickness of 0.12 mm. The grey, shaded area represents the time (5 min) before the light was turned on. When the intensity was increased beyond 20 mW/cm2, the reaction rate did not significantly change.
