摘　　要：本文对对二甲胺基二苯酮的吸收光谱及其光敏引发甲基丙烯酸甲酯聚合反应动力学进行了研究，并简单考察了氧气对聚合反应的影响。In this paper,the photopolymerization of Methyl Methylacrylate initiated by 4-(dimethylamino)benzophenone and its absorptoin spectrosopic behavior has been studied.The photopolymerization rate equation and its overall activation energy was obtained as follows: R p∝ 0.27 0.82 ,Ea=5.22kcal/mol.The effect of oxygen on the polymerization rate was also revealed.
