| 中文摘要: |
| 用机械共混法制备了具有互穿聚合物网络(IPN)结构的氯磺化聚乙烯(CSM)/SBR共混物。研究了共混组分、混炼温度和混炼时间对共混物力学性能的影响。结果表明，当CSM/SBR的共混比为20/80时，共混物的扯断伸长率达到最佳值；共混比为80/20时拉伸强度达到最大值；共混条件以70 ℃×10 min为宜。橡胶通过简单的机械共混，经分别交联后可形成较理想的非典型IPN复合材料。 |

| The chlorosulfonated polyethylene(CSM)/SBR blend with interpenetrating network(IPN) was prepared with the mechanical blending method.The influence of the blending ratio，temperature and time on the physical properties of blend was investigated.The results showed that the maximum elongation at break of blend was obtained with the CSM/SBR blending ratio of 20/80；the maximum tensile strength was obtained with the CSM/SBR blending ratio of 80/20；and the suitable blending condition was 70 ℃×10 min.A non-typical IPN type composite was obtained by simple mechanical blending and respective crosslinking of two components. |
