| 中文摘要: |
| 通过对比分析红外光谱法、核磁共振法和碘值法3种主要氢化丁腈橡胶（HNBR）结构表征方法，简化了红外光谱法测定不饱和度的计算公式，提出了红外光谱法、核磁共振法HNBR生胶结合丙烯腈含量计算方法，分析了计算结果与实测数据差异的原因，利用数值差异可对生胶结构组成简单定性，并对未知HNBR牌号生胶类型进行推断。 |
| 英文摘要: |
| By comparing and analyzing three main structural characterization methods for hydrogenated nitrile rubber（HNBR） using infrared spectroscopy，nuclear magnetic resonance，and iodine value methods，the calculation formula for measuring unsaturation using infrared spectroscopy was simplified.The calculation methods for the bound acrylonitrile content of HNBR raw rubber using infrared spectroscopy and nuclear magnetic resonance were proposed，and the reasons for the difference between the calculation results and the test data were analyzed.The data difference could be used to qualitatively determine the structural composition of the raw rubber，and to infer the type of raw rubber with unknown HNBR grades. |
