Ultraviolet photopolymerization induced by a triazine derivative

Authors


Abstract

2-(3,4-Methdioxyphenyl)-4,6-bis(trichloromethyl)- 1,3,5-triazine (MBTTR) was used as a photoinitiator for the polymerization of acrylate monomer. Ultraviolet–visible absorption spectroscopy was used to investigate the photochemical behavior during the photophysical process. The photopolymerization kinetics were monitored by real-time Fourier transform infrared spectroscopy. The polymerization rates of the acrylates were significantly higher than those of the methacrylates. When MBTTR induced the polymerization of trimethylolpropane triacrylate, there was an optimum polymerization rate and the final conversion was obtained at 0.1 wt % MBTTR. MBTTR was an inefficient photoinitiator for ethyl vinyl. The final conversions of tripropylene glycol diacrylate induced by MBTTR and triazine/1,3-benzodioxole were similar. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
