| 1 | Development proposals of isoprene rubber in China were put forward. | |
| 2 | This article introduces the research progress of rare-earth IR at home and abroad in recent years. | |
| 3 | Luhua isoprene rubber (LHIR) is a kind of solution-polymerization polyisoprene with high cis-1,4 content and high molecular weight. | |
| 4 | This is because they have a quiet similar microstructure, so isoprene rubber has the same excellent combination properties with natural rubber in performance. |
