Comparison of the reaction kinetics of eosin-initiated polymerization with monomer that has been purged with argon for 20 minutes immediately prior to reaction (black line) versus monomer that has not been treated to reduce dissolved oxygen content (grey line). The initiator is eosin-ITC and the monomer is 420 mM PEGDA, 210 mM MDEA, and 35 mM VP in water. Samples were in a sealed 0.5 mm thick sample holder and were exposed to 75 mW/cm2 >480 nm light and the light was turned on at time equal to zero in all experiments.
