采用核磁共振波谱法对聚环戊烯橡胶进行一维氢谱和碳谱分析，结合二维核磁HSQC（Heteronuclear Single Quantum Coherence）方法，对聚环戊烯橡胶顺反异构体核磁谱峰进行归属。建立了聚环戊烯橡胶顺反异构体含量计算公式，根据该公式计算得到聚环戊烯橡胶顺反异构体含量。将本方法定量结果与红外法定量结果进行比对，结果显示，核磁共振波谱法更适合于聚环戊烯橡胶顺反异构体定量分析。
採用覈磁共振波譜法對聚環戊烯橡膠進行一維氫譜和碳譜分析，結閤二維覈磁HSQC（Heteronuclear Single Quantum Coherence）方法，對聚環戊烯橡膠順反異構體覈磁譜峰進行歸屬。建立瞭聚環戊烯橡膠順反異構體含量計算公式，根據該公式計算得到聚環戊烯橡膠順反異構體含量。將本方法定量結果與紅外法定量結果進行比對，結果顯示，覈磁共振波譜法更適閤于聚環戊烯橡膠順反異構體定量分析。

Nuclear magnetic resonance (NMR) method including one-dimensional hydrogen spectrum and carbon spectrum was used for analysis of polycyclopentene rubber. By the aid of 2D NMR (HSQC), the identification for the NMR peaks of cis-trans isomers in polycyclopentene rubber was completed. Finally, a simple calculation formula for the quantitative analysis of cis-trans isomer in polycyclopentene rubber was established. The content of cis-trans isomers in polycyclopentene rubber was obtained by this calculation formula. The quantitative results obtained by NMR were compared with those obtained by IR, it was showed that NMR method was more suitable for quantitative analysis of cis-trans isomer in polycyclopentene rubber.
