| 摘 要： | 利用傅里叶转变红外光谱(FTIR)定量分析聚乙二醇/聚乙烯共混物组成，对特征谱带的选择，重叠峰的分离，数据的拟合处理作了详细讨论。采用1 378 cm-1处聚乙烯的复合峰与1 110 cm-1处聚乙二醇的复合峰强度比作为定量分析的基准，利用基于Beer-Lambert定律的理论拟合方程能较好的实现峰强度比与组分浓度的对应关系，可满足聚乙二醇/聚乙烯共混物组分的定量分析的要求。

| Abstract: | The concentration of the component of PEG/PE blends was analyzed quantitatively by infrared spectrascopy. The absorption peak area ratio of the selected mixture peaks used as the calibrating basis for the quantitative analysis was more reasonable than the peak area ratio of the pure peaks. The theoretical equation deducted by Beer -Lamber law was used to establish the working curve to calculate the composition of the responding functional groups in the film of the PEG/PE blends. The characteristic peaks of the crystal can not be selected as the calibrating basis for the quantitative measurement, because the crystallization has a great effect on the intensity of the absorption peaks. |
