摘要： 以 ４－氟－４′－羟基二苯甲酮和丙烯酰氯为原料，采用酰基化反应合成了一种含氟可聚合二苯甲酮类光引发剂（ＦＢＰＡｃ）。 通过紫外光谱研究了 ＦＢＰＡｃ 的吸收、降解以及迁移性能，并利用实时红外（ＲＴ－ＩＲ）研究了 ＦＢＰＡｃ 的光聚合动力学行为。 结果表明：ＦＢＰＡｃ 的最大吸收峰在 ２５６.２ ｎｍ处，与二苯甲酮（ＢＰ）最大吸收峰（２５１.０ ｎｍ）相比略微红移；ＦＢＰＡｃ 的相对迁移率仅为 ＢＰ 的 １５％。

Abstract: A polymeric photoinitiator containing fluorine (FBPAc)was prepared by using 4-fluorophenyl-4'-hydroxyphenyl benzophenone and acryloyl chloride as raw materials via an acylation reaction. The Uv-vis absorption spectra was applied to study the absorption, degra-dation and migration performance of FBP. The real-time infrared spectroscopy (RT-IR) was used to investigate the photopolymerization kinetics of FBPAc. The results showed that the maximum absorption peak of FBPAc was 256. 2 nm and gave a little red shift as compared with BP(251.0 nm). Moreover, the relative migration rate of FBPAc was only 15% of BP.
