| 摘 要： | 对在He-Ne激光诱导下,甲苯胺蓝(TB)-三乙醇胺(TEOA)分别在乙二醇(EG)-H_2O和EG溶液增感丙烯酰胺(AM)的聚合动力学进行了研究,TB-TEOA的光氧化还原反应受EG粘度和极性的影响,TB褪色速率随EG浓度的升高而降低.在一定粘度范围内,AM聚合适率随EG粘度的提高而明显增加;AM聚合表观活化能在EG比在水溶液要高。测定了大分子链自由基向EG分子的转移常数并确定了其在EG溶液中的表观聚合动力学方程.

| Abstract: | The polymerization kinetics of acrylamide(AM) induced by He-Ne laser with toluidine blue (TB)-triethanolamine(TEOA) as the sensitizing system has been investigated in glycol(EG)-H2O solution and in EG solution, respectively. The photoredox of TB-TEOA is influenced by the higher viscosity and polarity of EG. The photofading rates of TB decrease with the raising of EG]. The effect of EG viscosity on the polymerization of AM is also significant. The overall apparent kinetic equation of polymerization in EG solution and the chain transfer constant for EG have been determined. The overall apparent activation energy of polymerization in EG is much higher than that in H2O system. |
