A water soluble methylated β-cyclodextrin/camphorquinone (MCD/CQ) complex, based on methylated β-cyclodextrin (MCD) and camphorquinone (CQ), was prepared and its structure was characterized by FTIR, 1H-NMR, and UV-vis spectra. The photopolymerization kinetics of MCD/CQ in the water soluble monomer system was studied by Real-time Infrared spectroscopy (RT-IR). Compared to the photopolymerization carried out under nearly identical conditions but without MCD, the polymerization rate and final conversion initiated by a CQ-triethanolamine photoinitiator system were slightly lower. The effects of different MCD/CQ concentration, triethanolamine concentration, and light intensity were also studied.
