【摘要】 <正> 近年来利用荧光光谱研究高分子光氧化降解过程,由于方法本身具较高的灵敏度,因而受到较多的注意,但由于高分子化合物所含发色团种类的局限性,以及生成的氧化产物不易在荧光光谱中检出,因此在一定程度上限制了该法的发展。最近Tovborg Jensen利用能量转移的办法研究高分子光氧化问题时指出:体系在氧化过程中生成的更多还原

【Abstract】 The original process of photooxidation of polystyrene has been studied by fluorescence spectra in this work. Some model compounds were applied to prove that the fluorescence quenching of polystyrene was related to the photooxidation products formed during the process of exposure.更多还原
