| 中文摘要: |
| 对比研究两种催化体系三元乙丙橡胶（EPDM），即基于茂金属催化体系制备的EPDM33与基于齐格勒-纳塔催化体系制备的EPDM4045的性能。结果表明：EPDM33与EPDM4045的性能差异主要源于相对分子质量分布和乙烯基含量的不同；纯EPDM33胶料的性能明显优于纯EPDM4045胶料；在优化配方的条件下，填充炭黑N550的EPDM4045胶料的性能得到显著改善，与相同配方的EPDM33胶料相当甚至更优。 |
| 英文摘要: |
| A comparative study was conducted on the properties of ethylene propylene diene monomer （EPDM） produced by two catalytic systems，namely EPDM33 prepared based on the metallocene catalytic system and EPDM4045 prepared based on the Ziegler-Natta catalytic system.The results showed that the property differences between EPDM33 and EPDM4045 mainly stemmed from the differences in molecular mass distribution and vinyl content.The properties of pure EPDM33 compound was significantly better than those of pure EPDM4045 compound.Under optimized formulation conditions，the properties of EPDM4045 compound filled with carbon black N550 was significantly improved，comparable to or even superior to those of EPDM33 compound with the same formulation. |
