光响应高聚物作为功能材料的组成部分已受到极大的关注。近年来利用光化学探针研究高聚物的结构、形态和分子运动不断有所报导。方法的特点是利用反应体系环境的变化引起探针分子光物理性质的响应,从而达到监测的目的。本文报导以N,N-二甲胺基苄叉丙二腈(DMABM)作探针分子研究酚醛环氧丙烯酸酯的光固化过程。
Photo-responsive polymers have received a great deal of attention as an integral part of functional materials. In recent years, the use of photochemical probe polymer structure, morphology and molecular motility continue to be reported. The method is characterized by the use of the reaction system environment changes caused by the probe photophysical properties of the response, so as to achieve the purpose of monitoring. In this paper, the photo-curing process of novolac epoxy acrylate with N, N-dimethylaminobenzaldmalononitrile (DMABM) as a probe was investigated.
