| 摘 要： | 利用红外光谱技术对六种新型水溶性硫杂蒽酮类光引发剂在紫外光聚合反应中的引发性能进行了测试，用相对峰面积法计算了聚合反应的转化率，并据此对引发剂结构与光化学性能之间的关系做了一定的探讨。结果表明该类光引发剂具有很高的光化学活性，而引发剂的结构直接影响引发性能。研究发现硫杂蒽酮母体上甲基的引入使引发剂的引发效率增大，而引发剂侧链上羟基的引入，则由于降低了质量转移的有效性并有可能使引发剂分子缔合，致命引

| Abstract: | By analyzing IR spectra of monomer SR604 with six novel photoinitiators of water-soluble thioxanthone type, the photopolymerization efficiencies of these initiators during UV curing process were compared. The rate of conversion was counted using relative absorption area method. The relationships between structure and photochemical properties were also discussed. |
