| 中文摘要: |
| 研究红外光谱法测定聚异戊二烯橡胶（IR）的顺式-1，4-结构含量。结果表明，通过测定红外光谱中顺式-1，4和3，4-结构双键上碳-氢键变角振动吸收峰的积分面积，并与核磁共振氢谱测定的二者比值相比较，确定二者红外光谱特征峰出峰效率校正因子，计算得出IR的顺式-1，4-结构含量。红外光谱法定量分析IR顺式-1，4-结构含量操作简单、快捷，结果准确。 |
| 英文摘要: |
| This paper presents a testing method to quantitatively determine the cis-1，4 structure content of IR by infrared spectroscopy.The C—H absorption peak areas of double bond in both cis-1，4 and 3，4 structures were measured and calibrated with 1H NMR measurement result.With the calibration factor，the cis-1，4 structure content was calculated. This method is simple，fast，and accurate. |
