摘　　要：用 13C核磁共振波谱法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乙烯及第三单体乙叉降冰片烯的含量 ,为红外光谱批量的定量分析建立了基准化的标定。Components of ethylene-propylene-diene rubber(EPDR) were quantitatively analyzed by 13C nuclear magnetic resonance spectrometry. The contents of ethylene and 5 _ ethylidene _ 2 _ norbornene in three 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.
