| 中文摘要: |
| 研究了改性方式、聚硅氧烷用量和聚合温度对有机硅改性丙烯酸酯橡胶性能的影响。结果表明，采用有机硅共聚改性（聚硅氧烷用量为15%，聚合温度为50℃），可显著改善丙烯酸酯橡胶的耐热性、耐寒性、耐水性及加工工艺性能，且硫化胶耐油性和力学性能变化不大，完全能满足作为耐热耐油密封件所用橡胶的要求。 |
| 英文摘要: |
| The effects of modifying method，polyorgano-siloxane content and polymerization temperature on the vulcanizate properties of silicone-modified AR were investigated. The results showed that the heat，cold and water resistance as well as the processibility of AR modified by the emulsion copolymerization with silicone were significantly improved without affecting the oil resistance and physical properties. |
