Abstract

A trifunctional photoinitiator based on commercial photoinitiators 2-hydroxy-2-methylpropiophenone (Irgacure1173) and 2-hydroxy-4'-(2-hydroxyethoxy)-2-methylpropiophenone (Irgacure2959) was synthesized by an esterization reaction. Its structure was characterized by UV-Vis spectrometry, Infrared Transformed Fourier, Proton Nuclear Magnetic Resonance Spectra, 13 Carbon Nuclear Magnetic Resonance Spectra, Mass Spectrometry, and Thermogravimetry. In addition, its photoinitiating activity was investigated. The results showed that the novel photoinitiator had good photoinitiating activity and thermal stability compared to commercial photoinitiators. The migration of the residual photoinitiator in the cured film was lower than that of 1173 and 2959.

摘要

基于商业光引发剂2-羟基-2-甲基苯丙酮（Irgacure1173）和2-羟基-4'-（2-羟基乙氧基）-2-甲基苯丙酮（Irgacure2959），通过酯化反应合成了一种三官能团光引发剂。通过紫外可见光谱、傅里叶变换红外光谱、质子核磁共振谱、碳-13核磁共振谱、质谱和热重分析法对其结构进行了表征。此外，还研究了其光引发活性。结果表明，与商业光引发剂相比，这种新型光引发剂具有良好的光引发活性和热稳定性。固化膜中残留光引发剂的迁移率低于Irgacure1173和Irgacure2959。
