N-取代N′-苯基哌嗪类化合物与硫杂蒽酮体系光诱导电子转移引发聚合体系的研究

A STUDY ON THE PHOTOINDUCED ELECTRON TRANSFER INITIATION POLYMERIZATION OF MMA BY SYSTEM OF N-SUBSTITUTED N'-PHENYLPIPERAZINE AND THIOXANTHONE

本工作对N-苯基-N'-乙基呱嗪作为酮/胺光引发体系中组分之一的作用机制进行了研究。发现该特殊的胺类化合物虽包括二甲基苯胺和三乙胺两个部分,但它和酮类相组合形成的光引发体系只有较低的尤引发速率。对上述现象进行了讨论,并通过加入酸类化合物使其中一个胺发生季胺盐化,用以改进光引发效率来进一步证实文中所讨论的机制。

In this work, the action mechanism of N-ethyl-N'-phenylpiperazine-one of components in the photo-initiation system has been studied. It was found that the titled amine in which although dimethyl aniline and triethyl amine both were contained, possesses less efficiency of photoinitiation while it was composed with ketone as an initiated system. This phenomenon was discussed and the mechanism was further comfirmed by the addition of acid for promoting of photoinitiated efficiency by the quaternary ammoniation of one of amines in piperazine.
