| 摘 要： | 以柠糠酸酐为原料, 合成了一种可以与丙烯腈(AN, acrylonitrile)共聚的新单体: 2-甲基-2-丁烯二酸单甲酯(MBAME). 以偶氮二异丁腈(AIBN, 2,2’-azobis isobutyronitrile)为引发剂, 70 ℃下引发MBAME与AN在N,N-二甲基甲酰胺(DMF, N,N-dimethylformamide)中进行无规共聚, 通过Fineman-Ross法测定了两者在DMF溶液聚合体系的表观竞聚率, γ1(AN)＝7.985, γ2(MBAME)＝0.599, 有助于优化聚丙烯腈基碳纤维用树脂的生产工艺. |

| Abstract: | A new methacrylate monomer, (Z)-2-methyl-2-butenedioic acid-1-methyl ester (MBAME), was synthesized using citraconic anhydride as starting material. This monomer can copolymerize with acrylonitrile in N,N-dimethylformamide at 70 ℃ using 2,2’-azobisisobutyronitrile as initiator. The apparent reactivity ratio of AN/MBAME copolymerization system calculated by Fineman-Ross method was 7.985 for AN and 0.599 for MBAME, respectively. This result may benefit the production of PAN-based carbon fiber. |
| Keywords: | (Z)-2-methyl-2-butenedioic acid-1-methyl ester acrylonitrile copolymerization reactivity ratio |
