| 中文摘要: |
| 以异戊二烯为单体，以新癸酸钕（Nd）、二异丁基氢化铝、氯化二乙基铝三元络合物为催化剂合成聚异戊二烯橡胶（Nd-IR），并分别与进口和国产钛系聚异戊二烯橡胶（Ti-IR）进行性能对比研究。结果表明：Nd-IR的顺式1，4-结构质量分数和硫化胶的物理性能均与Ti-IR相当；Nd-IR用于轮胎胎面胶具有较好的抗湿滑性能和较低的滚动阻力，且适用于冬季轮胎胎面胶。 |
| 英文摘要: |
| Rare earth neodymium polyisoprene rubber（Nd-IR） was prepared by using isoprene as monomer，and ternary complex of neodymium neodecanoate，diisobutyl aluminum hydride and diethyla-luminum chloride as catalyst.The properties of Nd-IR，imported and domestic rare earth titanium polyisoprene rubber（Ti-IR） were comparatively investigated.The results showed that，the mass fraction of cis 1，4 units of Nd-IR and physical properties of Nd-IR vulcanizate were similar to Ti-IR.The tire tread compound with Nd-IR possessed better wet skid resistance and lower rolling resistance，and thus it could be applied in winter tire tread. |
