摘要

以4-(2,3-环氧丙氧基)二苯甲酮与全氟辛酸为原料制备了含氟光引发剂十五氟辛酸1-(4-苯甲酰-苯氧甲基)-2-羟基乙酯（EBPFOA）。通过红外光谱（FT-IR）和核磁共振（19F NMR）对EBPFOA进行了结构表征；通过紫外吸收光谱测定了EBPFOA的紫外光吸收能力；采用实时红外光谱（RT-IR）考察光强和光引发剂浓度等对EBPFOA单体的双键转化率和聚合速率的影响，并研究了其抗氧阻聚性能。结果表明，随着光强的增加，单体的双键转化率和聚合速率增加；在一定的范围之内，引发剂的浓度越高，双键转化率越高，聚合速率越快，并具有良好的抗氧阻聚性。

Abstract

Pentadecafluoro-octanoic acid 1-(4-benzoyl-phenoxymethyl)-2-hydroxy-ethyl ester(EBPFOA) was synthesized with (4-Oxiranylmethoxy-phenyl)-phenyl-methanone (EBP) and Pentadecafluorooctanoic acid (PFOA), which was characterized by FT-IR, 19F NMR, and UV absorption spectra. Real time infrared spectroscope (RT-IR) was applied to investigate the effects of different monomer system, various light intensity and concentration of photo-initiator on the polymerization kinetics and the ability of EBPFOA to overcome oxygen inhibition. The results indicate that the rate of polymerization (Rp) and final double bond conversion increase with increasing light intensity. In a certain range, the higher the concentration of initiator, the higher the double bond conversion and the faster the Rp. EBPFOA shows good ability to overcome the oxygen inhibition.Cited
