摘　　要：研究了He-Ne激光诱导在丙烯酰胺(AM)存在下甲苯胺蓝(TB)-三乙醇胺(TEOA)水溶液体系的光褪色动力学。光谱显示,AM存在下TB缔合平衡向单分子体方向移动,因此TB光褪色较快。研究表明,AM与TB相互作用形成以1:1配位的络合体。本文也研究了以TB-TEOA作为增感体系AM的光聚合作用。聚合速率正比于初始单体浓度的1.4次方。The photofading kinetics of aqueous toluidine blue(TB) triethanolamine(TEOA) in the presence of acrylamide(AM) induced by He-Ne laser has been investiga- ted. Spectra showed that the association equilibrium of TB shifted to the mono- meric form in the presence of AM, thus the photofading of TB was faster. The results indicated that a complex of AM and TB with coordination number of 1:1 formed due to their interaction. The photopolymerization of AM with TB-TEOA as the sensitizing system was also investigated. The rate of polymerization was proportional to 1. 4 power of the initial monomer concentration.
