摘要
衰减全反射作为红外光谱法的重要实验方法之一,快速、简单、不破坏样品,极大地扩展了红外光谱的应用领域。用红外光谱技术分析了几种常见高聚物的红外光谱图,通过这些红外光谱图的特征峰可以有效确定聚合物的类型。最后以乙烯-醋酸乙烯酯共聚物(EVA)为例讨论了该技术在共聚物或共混物组成测定方面的应用。
The attenuated total refraction infrared spectroscopy （ATR-FTIR）is an important experimental method, it greatly expands the application fields of infrared spectroscopy. Several kinds of polymer materials were analysed by ATR-FTIR. The infrared spectrum characteristic peaks can effecticely determine the type of polymer. Infrared spectroscopy can also be applied in the composition determination of the copolymer or blend.
