| 中文摘要: |
| 对国产与进口稀土顺丁橡胶（NdBR）的性能进行对比研究。结果表明，相对于两个牌号的进口NdBR，国产NdBR9104的顺式-1,4结构含量较高，相对分子质量及其分布接近，混炼胶加工性能较优，硫化胶的拉伸性能、耐磨性能和耐屈挠性能均较好。国产NdBR 9104完全可以替代同类进口产品使用。 |
| 英文摘要: |
| Comparative study on the properties of domestic and imported neodymium butadiene rubber（NdBR） was carried out.The results showed that compared to two brands of imported NdBR，the cis-1，4 structure content of domestic NdBR9104 was higher，the relative molecular weight and its distribution were similar，the processing property of the compound was better，and the tensile property，wear resistance and flexural resistance of the vulcanizet were all better.Domestic NdBR9104 could completely replace imported similar products. |
