摘　　要：采用实时红外技术对所合成的活性稀释剂吡咯烷基-N-甲酸-丙烯酸乙二醇酯的聚合动力学进行了测试.研究了光强、引发剂浓度及引发剂种类对其光聚合的影响.结果表明:光强越强、引发剂浓度越大,聚合速率越高,但是反应的最终双键转化率基本不变,均能达到100%左右.引发剂种类对其光聚合的最终双键转化率的影响不是特别明显,但对聚合速率有一定的影响.The kinetics of 2-（acryloyloxy）ethyl pyrrolidine-l-carboxylate was studied by real time infrared spectroscopy（RTIR）. The influences of light intensity, initiator concentration and different initiators on the kinetics were investigated in this paper. It showed that higher light intensity and initiator concentration had higher curing rate, but the final double bond conversion was almost the same, about 100%. Different kinds of initiator had the same final conversion, but would influence the curing rate.
