摘　　要：本文以4-羟基二苯甲酮和溴丙烯为原材料合成了一种含二苯甲酮结构的光引发剂(POBP)。通过核磁共振谱图确定了其结构;利用紫外吸收谱图研究了其紫外吸收和光降解性能;最后通过了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,POBP最大吸收波长相对二苯甲酮(BP)红移了33.6nm,且其吸光能力大大增强,引发HDDA效率较传统二苯甲酮的提高也意味着POBP是一种很好的光引发剂。This paper used 4-hydroxyphenyl benzophenone and allyl bromide as materials synthesized a photoinitiator containing benzophenone.Its structure was determined by NMR spectroscopy.The absorption and degradation performance of POBP were studied by UV-vis absorption spectra.Real-time infrared spectroscopy（RT-IR）investigated the influence of the concentration of POBP,light intensity and monomer on Polymerization kinetics.The results show that the maximum absorption wavelength of POBP has a notable red shift compared with BP.And its light absorption ability is greatly enhanced,which leads to the double bond conversion of HDDA has an improvement,which also means that POBP is a good photoinitiator.
