摘　　要：采用实时红外技术研究了樟脑醌(CQ)/脂肪胺可见光引发牙科复合树脂聚合的动力学过程。考察了不同胺链长、胺浓度以及光强对牙科修复复合树脂光聚合动力学的影响。结果表明:随着链长的增加,反应速率和转化率都有一定程度的降低,增加引发体系的浓度和增加光强都可以增加反应速率和转化率。Real time FTIR was used to monitor the kinetics of dental resins polymerization photoinitiated by mixtures of camphorquinone （CQ）/aliphatic tertiary amines. The effect of concentrations of amines, the chain length of amines and light intensity on the kinetics was investigated. The results showed that, increasing the chain length of the amines led to the decrease of the double bond conversion and rate of polymerization （Rp）. With the increase of the concentration of amines and the light intensity, the double bond conversion and Rp both increased.
