摘要/Abstract

摘要： 本文先以4-甲基二苯甲酮合成4-（溴甲基）二苯甲酮，然后用4-羟基二苯甲酮和4-（溴甲基）二苯甲酮为原材料合成了一种含二苯甲酮结构的新型光引发剂（MBPBP）。通过核磁共振氢谱图确定了其结构；利用紫外吸收谱图研究了其紫外吸收和光降解性能；最后通过RT-FTIR分析了光引发剂浓度、光照强度和反应单体对光聚合反应的影响。结果表明，MBPBP的摩尔消光系数约为二苯甲酮的1.5倍，吸收范围大大增加，延伸到300 nm，吸光效率获得大幅提高，光引发活性远大于传统的二苯甲酮，是一种高效光引发剂。

关键词: 光聚合, 光引发剂, 二苯甲酮, 高效光引发

Abstract: In this paper, 4-(bromomethyl) benzophenone was synthesized from 4-methylbenzophenone. Then, a new type of photoinitiator (MBPBP) containing benzophenone structure was synthesized by using 4-hydroxybenzophenone and 4-(bromomethyl) benzophenone as raw materials. The structure was determined by ¹HNMR spectroscopy. The UV absorption and photodegradation properties were studied by UV absorption spectroscopy. The effect of photoinitiator concentration, light intensity and reaction monomer on photopolymerization was analyzed by RT-FTIR. The results show that the molar extinction coefficient of MBPBP is about 1.5 times of that of benzophenone, and the absorption range is increased to 300 nm. The light absorption efficiency is much higher than that of the traditional benzophenone. It is a kind of efficient photoinitrogenation agent.

Key words: photoinitiation, photoinitiator, benzophenone, efficient light trigger
