| 中文摘要: |
| 介绍稀土催化剂、稀土促进剂和稀土防老剂的应用研究进展。稀土催化剂体系一般由多个组分组成，稀土化合物作主催化剂。通过控制组分的配合、控制配位反应，可提高催化体系的效率与性能。稀土催化剂主要用于丁二烯橡胶和异戊橡胶的合成。稀土促进剂（镧、钕、铕等的配合物）可改善天然橡胶、丁苯橡胶等的加工安全性能和物理性能，应用前景广阔。稀土配合物（镧配合物）与常用防老剂复配可提高橡胶的耐热氧老化、耐臭氧老化和耐屈挠疲劳等性能，防护效果好。 |
| 英文摘要: |
| In this paper，advances in the catalyst，curing accelerator and antioxidant using rare earth compounds are reviewed.Rare earth catalyst systems are generally composed of several components in which rare earth compound is used as the primary catalyst.By matching the components with controlled coordination reaction，the efficiency and performance of the catalytic system are improved.Rare earth catalyst is mainly used for production of butadiene rubber and isoprene rubber.Rare earth accelerators (for example，complexes of lanthanum，neodymium or europium) can improve the processing safety and physical properties of natural rubber and styrene butadiene rubber，showing promising application potential.Lanthanum complex can be used jointly with conventional antioxidant to improve the thermal oxidative aging resistance，ozone aging resistance and flex fatigue resistance of rubber vulcanizates. |
