摘要
为提高传统硫杂蒽酮光引发剂的引发活性,通过环氧基团的开环反应合成了含胺硫杂蒽酮光引发剂2-[2-羟基-3-(2-羟乙基-2-甲基)氨基]丙氧基硫杂蒽酮(APTX)。傅立叶变换红外光谱和核磁共振氢谱证实了APTX的结构。紫外光谱表明取代基的存在使硫杂蒽酮单元的最大紫外吸收波长发生红移。以硫杂蒽酮(TX)为参照,用光致差示扫描量热计(Photo-DSC)研究了三羟甲基丙烷三丙烯酸酯(TMPTA)的光聚合反应,结果表明,APTX可更有效地引发TMPTA的光聚合。
In order to promote the photo-efficiency of traditional thioxanthone photo-initiators, 2-[2-hydroxy-3-（2-hydroxyethyl-2-methyl）amino]propoxy-thioxanthone（APTX） containing coinitiator amine was synthesized by using the ring-opening reaction of epoxy group. FT-IR and 1H-NMR analyses confirmed the structures of APTX. UV-Vis spectra showed that the maximal absorption wavelength of thioxanthone moieties became red-shift as the existence of substituents. The photo-polymerization of trimethylolpropane triacrylate （TMPTA） was made by use of photo differential scanning calorimetry （photo-DSC）. The results show that APTX can effectively initiate the photo-polymerization of TMPTA.
