| 摘 要： | 本文研究了二苯酮/三乙胺/氧体系引发MMA的光聚合反应中烷基铵羧酸盐类(R1R2R3R4N+O-OCR5)离子型表面活性剂的催化作用。实验结果表明,聚合速度的大小和表面活性剂的类型,分子结构以及浓度有关。表面活性剂分子对系统中氢过氧化物光敏分解的促进,使聚合反应的量子产率提高了两倍多。

| Abstract: | The catalytic action of some ionic surfactants of alkylammonium carboxylate type in the photopolymerization of MMA initiated by benaophenone/triethylamine/oxygen system has been studied. Experimental results show that the rate of polymerization depends upon the type, molecular structure and concentration of the surfactant. As a result of the accelerating effect of the surfactants on photosensitized decomposition of hydroperoxides formed in the system, the qiantum yield in the photopolymerization is increased by 2 times. |
