| Abstract: | Two kinds of quaternary ammonium tetraphenylborates(QA salt-BPh_4) have been synthesized and characterized by elemental analysis, nuclear magnetic resonance spectroscopy and UV spectroscopy. The polymerization of tri- methylolpropane triacrylate(TMPTA) initiated by them under UV light illumination appeared to be radical polymerization and could be inhibited by oxygen. It was found from the results of photo-DSC of TMPTA at different temperature that the photoinitiation efficiency increased with polymerization temperature and the activation energy was calculated to be 44.4 kJ/mol. Thermogravimetry proved that the product had very good thermostability. |
