| 中文摘要: |
| 主要介绍稀土顺丁橡胶（BR）、稀土异戊橡胶（IR）和稀土丁异戊橡胶（BIR）的生产和研究状况。钕系BR（Nd-BR）是BR中顺式含量最高（顺式-1，4-结构物质的量分数可达0.98以上）、综合性能最好的胶种，将替代其他BR成为高性能子午线轮胎的主要原料。稀土IR合成技术为我国首创，钕系IR（Nd-IR）主要应用于医用器械领域，钛系IR（Ti-IR）和Nd-IR主要应用于轮胎中。而钕系BIR（Nd-BIR）脆性温度低于－80 ℃，Nd-BIR在低温材料和轮胎中具有广阔应用前景。 |
| 英文摘要: |
| In this paper，the production and research status of rare earth butadiene rubber（BR），rare earth isoprene rubber（IR） and rare earth butadiene isoprene rubber（BIR） are introduced. Nd-BR has the highest content of cis-structure in all types of BR materials with the cis-1，4-structure content of 0. 98 or more， it possesses the best comprehensive performance and will replace the other BR as the main raw material for high-performance radial tire. The synthesis technology of rare earth IR was firstly developed in China. Nd-IR is mainly used in the field of medical equipments，and Ti-IR and Nd-IR are mainly used in tires. The brittle temperature of Nd-BIR is lower than －80 ℃，and so Nd-BIR is showing broad application prospects in low temperature materials and tires. |
