摘　　要：以 2 -乙二醇烯丙基醚 (AE)为活性稀释剂 ,研究了其与环氧丙烯酸酯 (EA)所组成的光聚合体系在光引发剂下的光固化动力学影响因素 .结果表明 :体系的聚合温度越高 ,体系的转化率越低 ;AE含量越大 ,体系的转化率越低 ;自由基 /阳离子混杂引发体系的引发效率明显高于单独使用阳离子或自由基型引发剂的体系 .The UV-curing kinetics of epoxy acrylate/allyl ether system has been studied. Allyl ether (AE) is used as a reactive diluent. The results have shown that the conversion of the system decreases with the increasing of the reaction temperature. The conversion of epoxy acrylate/allyl ether system decreases with the increase of concentration of AE. The UV-curing rate with hybrid initiating system is faster than both that of cation and free radical photoinitiators.
