| 中文摘要: |
| 考察国产钕系顺丁橡胶（NdBR）各项性能，并与进口NdBR及镍系顺丁橡胶（NiBR）进行对比。结果表明：与NiBR相比，NdBR具有较高的顺式1，4-结构含量和平均相对分子质量，相对分子质量分布较窄；NdBR与炭黑的结合能力强，加工性能好；NdBR的门尼焦烧时间和硫化速率均能满足安全加工的需要；国产NdBR硫化胶的物理性能可达国外同类产品水平。 |
| 英文摘要: |
| The properties of domestic NdBR were studied and compared with imported NdBR and NiBR.The results showed that the physical properties of domestic NdBR were similar to those of the imported NdBR.In general， the cis-1，4 content and average molecular weight of NdBR were higher than those of NiBR，respectively，and the molecular weight distribution was narrower.The bonding with carbon black and processing property of NdBR were excellent.The Mooney scorch time and curing rate of domestic NdBR could meet the need of processing requirements. |
