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.
