光引发剂在微乳液体系中所处的位置是微乳液光引发聚合反应引发机理研究的关键之一．利用紫外吸收光谱对不同环境中的光引发剂进行考察，但由于其吸收光谱没有明显的变化，因而未能获得较确切的结论［１，２］．本工作研究了光引发剂α－羟基－α，α－二甲基－（对－羟乙... The location of photoinitiator in the microemulsion system is one of the key points in the investigation of the initiation mechanism of photoinitiated polymerization in microemulsion. UV photoinitiators were used to investigate photoinitiators in different environments. However, due to no obvious changes in their absorption spectra, no definite conclusion was obtained [1, 2]. This work studied the photoinitiator α-hydroxy-α, α-dimethyl - (p-hydroxyethyl ...
