摘　　要：研究稀土异戊橡胶(Nd-IR)在全钢载重子午线轮胎胎面中的应用。根据傅里叶转换红外光谱和核磁共振谱,Nd-IR的顺式1,4-结构摩尔分数大于0.98且不含有反式1,4-结构,所有的序列单元与天然橡胶(NR)一样,均以"头-尾"方式键接。Nd-IR的物理性能与NR相差不大,将其以60%的比例替代NR用于全钢载重子午线轮胎胎面胶,加工性能不受影响,轮胎的各项性能均合格,其中耐久性能远高于全NR生产的轮胎。The application of neodymium isoprene rubber（Nd-IR）in the tread compound of truck and bus radial tire was investigated.Fourier transform infrared（FTIR）spectroscopy and nuclear magnetic resonance（NMR）spectroscopy were carried out to characterize the structure of Nd-IR.The test results showed that the content of cis 1,4-configuration in Nd-IR was above 98%,trans 1,4-configuration could not be detected,and all repeating units of Nd-IR presented ＂ head-to-tail＂ structure,which was same as natural rubber（NR）.The mechanical properties of Nd-IR did not show significant difference with NR.By using Nd-IR to replace 60% of NR by weight in the tread compound of truck and bus radial tire,the processibility of the compound was not affected,the tire performance was qualified,and the endurance performance was much higher.
