摘要：

Two novel kinds of low migration photoinitiators BRA and TXRA based on benzophenone (BP) and thioxanthone (ITX) were synthesized and used as Type II polymerizable photoinitiators. The structures were confirmed by proton nuclear magnetic resonance (H-1 NMR), carbon nuclear magnetic resonance (C-13 NMR), FT-IR and high resolution MS. The spectral properties were studied by Ultraviolet-Visible (UV-vis) spectroscopy. The photo-initiating activity of the initiators was evaluated by real-time RT-IR in the presence of a hydrogen donor such as triethylamine. The results show that they exhibited almost similar initiating activity as the reference BP or ITX, while exhibiting more low migration than the non-functionalized BP or ITX. These results suggest that BRA or TXPA is an efficient photoinitiator for reducing migration in photo-curing system.
