中文摘要：

用甲基丙烯酰氯分别与二乙醇胺和三乙醇胺反应合成了两种三官能度甲基丙烯酰氧基单体.以实时红外光谱（RT-IR）法研究了两种单体的光聚合动力学性质，考察了不同单体、不同引发剂和引发剂浓度、不同光强对聚合性能的影响，并采用动态力学分析仪（DMA）测试了光固化后材料的力学性能.结果表明，随着引发剂浓度的增大，单体转化率、最大反应速率都增大，随着光强的增大，单体转化率、最大反应速率都降低.与二苯甲酮（BP）相比，2-羟基-2-甲基-1-苯基丙酮（1173）对两种单体具有较好的引发效果.两种单体加入三缩四乙二醇双甲基丙烯酸酯（SR209）中后，对体系光固化后的产物力学性能有不同影响.

英文摘要：

Two trifunctional monomers based on diethanolamine （or triethanolamine） and methacryloyl chloride were synthesized and characterized by 1H-NMR, real-time infrared spectroscopy （RTIR） and dynamic mechanical thermal analysis （DMA）. The results showed that both rate of polymerization and final conversion increased with increase of photoinitiator concentration, and decreased with increase of light intensity. 2-Hydroxy-2-methyl-1-phenyl propan-1-one （1173） was a more effective photoinitiator to these monomers than that of benzophenone （BP）. As the addition of the two monomers to Tetraethylene Glycol Dimethacrylate （SR209）, the mechanical properties of the curing products were different.
