| 摘 要： | 合成了３种环状碘鎓盐，表征了它们的紫外吸收光谱特征，研究了碘盐－酮－胺三元引发体系引发丙烯酸？－羟乙酯（ＨＥＡ）－三羟甲基丙烷三丙烯酸酯（ＴＭＰＴＡ）的自由基聚合，结果表明，向酮－胺体系中加入环状碘盐可大大加快聚合速度。根据实验结果，推出了光引发机理。

| Abstract: | Three cyclic iodonium salts having different anions were synthesized and their UV spectra were analyzed. The HEA and TMPTA free radical polymerization experiments were made which were initiated by a three-component initiating system on a new cyclic iodonium salt/ketone/amine combination. The results show that the addition of cyclic iodonium salt to the usual ketone/amine system mostly result in a increase of the rate of polymerization. The niechanism of photoinitiation was deduced from the above itsults. |
