| 摘 要： | 采用傅立叶红外光谱仪、核磁共振仪对阳离子光引发剂4-(苯硫基)苯基二苯基硫鎓六氟磷酸盐(DPPH)结构进行了表征,紫外光谱分析表明该引发剂在302nm处有最大紫外吸收。通过实时红外(RT-IR)对DPPH引发丙烯酸酯单体光聚合动力学过程进行了研究,考查了引发剂浓度、光强及不同官能度单体对双键转化率及聚合速率的影响。随引发剂浓度增加,最大转化速率先增大后减小,而光强增加,最大转化速率增加。单体官能度越高,双键转化率与最大转化速率越低,达最大转化速率的时间越长。

| Abstract: | A cationic photoinitiator diphenyl(4-phenylthio)phenylsu fonium hexafluorophosphate( DPPH)has been synthesized.The structure of DPPH was identified by FTIR and 1H NMR spectrum,and UV spectrum showed that the maximum absorption wavelength was 302 nm.The photopolymerization kinetics was studied by real-time infrared spectroscopy(RT-IR).The results showed that the maximum polymerization rate largely depended on the initiator concentration, while the polymerization rate increased with the increase of light inte... |
