摘　　要：用核磁共振氢谱法(1 H-NMR)对三元乙丙橡胶进行了研究,通过图谱中各个峰的积分值,并用特定的计算公式测定了三元乙丙橡胶中C2、C3及第三单体乙叉降冰片烯(ENB)的含量,以期为红外光谱(IR)的定量分析提供参考校准数据。Components of ethylene-propylene-diene rubber （EPDR） were quantitatively analyzed by 1 H nuclear magnetic resonance spectrometry. The contents of C2, C3 and 5-ethylidene-2-norbornene in several samples of EPDR were determined using a calculation method through the integral areas of peaks. The results of this work could be used for calibration of quantitative analysis in a large scale by infrared spectrometry.
