| 摘 要： | 以4-(2,3-环氧丙氧基)二苯甲酮(EBP)和丙烯酸为原料,通过开环反应合成了含有不饱和双键的可聚合光引发剂4-(丙烯酸-2-羟基丙酯-3-氧基)二苯甲酮(AEBP).采用红外光谱(FT-IR)、核磁共振氢谱(1HNMR)对其结构进行表征,利用紫外吸收光谱对AEBP的紫外吸收波长进行表征,通过实时红外(RT-IR)研究了AEBP引发丙烯酸酯单体的光聚合动力学.采用萃取法对比了BP与AEBP引发固化体系后的迁移性.结果表明,随AEBP浓度增加,单体最终转化率增加;当助引发剂N,N-二甲氨基苯甲酸-乙酯(EDAB)浓度为1.2%时,单体最终双键转化率最高;AEBP对双官能度单体的引发效率较之三官能度单体的好;聚合速率随光照强度的增强而变快;固化后AEBP的迁移性比传统的BP大大降低.

| Abstract: | The curable photoinitiator of 4-(acrylate-2-hydroxypropylate-3-oxy) benzophenone(AEBP) containing unsaturated double bond was synthesized by 4-(2,3-epoxypropoxy) benzophenone(EBP) and acrylic acid through ring-open reaction method.The chemical structure was characterized by FT-IR and 1HNMR.The UV absorption wavelength of AEBP was characterized by UV-Vis spectrum.The photopolymerization kinetics of AEBP were investigated by RT-IR,extraction method was applied to compare the migration of BP with AEBP after cured.The results showed that double bond conversion increased with the increase of AEBP concentration,when EDAB concentration was 1.2%,the final double bond conversion was the optimum,the initiating efficiency of AEBP with diacrylate monomer were better than that with triacrylate monomer.The rate of polymerization increased with light intensity.After cured with monomers,the migration of AEBP reduced greatly compared with that of traditional BP. |
