| 中文摘要: |
| 采用溶液聚合法制备三元乙丙橡胶（EPDM）/丁腈橡胶（NBR）并用胶增容剂丙烯腈（AN）接枝EPDM（PAN-g-EPDM）共聚物，研究AN/EPDM用量比、引发剂BPO用量、溶剂种类、反应温度和反应时间对接枝率的影响。结果表明，在AN/EPDM用量比为5/6、引发剂BPO质量分数为0.005、溶剂为正庚烷、反应温度为70 ℃、反应时间为2.5 h的最佳溶液聚合反应条件下，PAN-g-EPDM共聚物的接枝率为26%，该接枝率的PAN-g-EPDM共聚物对EPDM/NBR并用胶增容性较好。 |
| 英文摘要: |
| The compatiblizer for ethylene-propylene diene rubber（EPDM）/nitrile rubber（NBR） blend，acrylonitrile（AN） grafted EPDM（PAN-g-EPDM），was prepared by solution polymerization，and the effects of the ratio of AN/EPDM，the amount of initiator BPO，solvent type，reaction temperature and reaction time on the grafting ratio were investigated.The results showed that the optimal reaction conditions were as follows：the ratio of AN/EPDM was 5/6，the mass fraction of initiator BPO was 0.005，the solvent was n-heptane，the reaction temperature was 70 ℃ and the reaction time was 2.5 h.The grafting ratio of obtained copolymer was 26% and the compatiblizing effect was good. |
