| 中文摘要: |
| 采用动态硫化方法制备NBR/聚十二内酰胺（PA12）热塑性硫化胶（TPV），研究硫化体系、NBR丙烯腈含量和NBR/PA12并用比对NBR/PA12 TPV性能的影响。结果表明，采用马来酰亚胺衍生物类硫化剂A/促进剂DM硫化体系，NBR/PA12 TPV呈两相海-岛结构，体系中PA12的结晶度较大，综合物理性能较好；NBR丙烯腈含量越大、在NBR与PA12总量不变的前提下，PA12用量越大，NBR/PA12 TPV综合物理性能和耐油性能越好。 |
| 英文摘要: |
| The NBR/polydodecalactam(PA12) thermoplastic vulcanizate（TPV） was prepared by dynamic vulcanization，and the influence of curing systems，acrylonitrile content of NBR and blend ratio of NBR/PA12 on the properties of NBR/PA12 TPV were investigated.The results showed that，using maleimide derivative vulcanizing agent A/accelerator DM curing system，NBR/PA12 TPV exhibited sea-island structure，the crystallinity of PA12 was high，and the comprehensive physical properties were good；the comprehensive physical properties and oil resistance of NBR/PA12 TPV were improved as acrylonitrile content of NBR and the addition level of PA12 increased. |
