title: [Quantitative analysis of two-component polymer blends (PEG/PE) by infrared spectroscopy].
abstract: The concentration of the camponent of PEG/PE blends was analyzed quantitatively by infrared spectroscopy. 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.
