摘要

利用紫外光谱对2,2'-二邻氯苯基- 4,4',5,5'-四苯基-1,2' –二咪唑（BCIM）光引发剂开展研究。以BCIM为光引发剂、4,4-二（N,N'-二甲基-氨基）苯甲酮（EMK）为光增感剂，N-苯基甘氨酸（NPG）为供氢体，通过实时红外光谱（RT-IR）研究丙烯酸酯单体在复合光引发体系中的光聚合动力学。结果表明：引发剂浓度越大，聚合速率越快，双键转化率越高；复合光引发体系中，当质量比m(BCIM): m(EMK): m(NPG)=10: 5: 5时，引发效率最高（96.7%）；双官能度单体引发效率较三官能度的好，双键转化率可达90%以上；聚合速率随光照强度的增强而变快。

Abstract

Photo-polymerization kinetics of acrylate monomer initiated by bis [2-(ochlorophenyl)-4,5-diphenylimidazole] compound photo-initiator system were investigated by real-time infrared (RT-IR), while NMR and UV was used for characterization, respectively. In synthetic system BCIM was used as pho-to-initiator, N, N-bis(diethylamino) benzophenone (EMK) was used as photo-sensitizer and N-phenylglycine (NPG) was used as hydrogen donor. The kinetics was determined by real-time infrared (RT-IR). The results showed that the polymerization rate and the double bond conversion increased with the initiator concentration while the mass ratio m(BCIM): m(EMK): m(NPG) was 10: 5: 5. The optimum initiate efficiency of 96.7% and the polymerization rate of above 90% with diacrylate monomer were better than that with triacrylate monomer. It was also found that the polymerization rate could increase with light intensity.Cited
