Cationic photopolymerizations of vinyl ethers were investigated using in situ, time-resolved fluorescence spectroscopy. Due to its intrinsic time scale, fluorescence spectroscopy provides a means to characterize these polymerizations which are too rapid to be monitored by traditional methods. The fluorescence intensity of the photosensitizer (anthracene or its derivatives) was monitored as a function of time with spectra collected in intervals as short as 2 ms.
