摘　　要：以实时红外光谱(RT-IR)法研究了合成的4-丙烯酰氧基二苯甲酮(4-ABP)的光聚合动力学性质,考察了不同单体、不同引发剂和助引发剂浓度、不同光强对聚合性能的影响.以萃取法对比研究了4-ABP和二苯甲酮(BP)在固化膜中的的残留量.结果表明,4-ABP是一种非常有效的光引发剂.随着引发剂浓度和光强的增大,单体转化率、最大反应速率都增大,诱导期缩短.萃取实验表明4-ABP在固化膜中的残留量远低于BP.The kinetics of photopolymerization of 4-aeryloylbenzophenone（4-ABP） was studied by Real-time Infrared spectroscopy, which showed that 4-ABP was a very effective photoinitiator. When the photoinitiator and amine were used to initiate polymerization of acrylates, both rate of polymerization and final conversion increased and the induction period shortened with increase of amine concentration, 4-ABP concentration and light intensity. For it is crosslinked in the cured film, the amount of extracted 4-ABP is much lower than that of BP
