| 摘要: |
| 以甲基丙烯腈（MAN）、甲基丙烯酸（MAA）和甲基丙烯酰胺（MAM）为主要单体原料，过氧化物引发共聚制得甲基丙烯腈-甲基丙烯酸-甲基丙烯酰胺（MAN-MAA-MAM）共聚物。详细研究了所制备共聚物的高温环化反应，以及所生成的聚甲基丙烯酰亚胺（PMI）的耐热性能。结果表明，MAN-MAA-MAM 共聚物的环化温度为160℃，所制备的聚甲基丙烯酰亚胺（PMI）在空气中可耐280℃的高温。 |

| Abstract: |
| Methacrylic acid-methacrylonitrile-methacrylamide(MAN-MAA-MAM) copolymer was synthesized by using peroxide as initiator and methacrlic acid, methacrylonitrile and methacrylamide as main raw materials. The cycle-reaction of the MAN-MAA-MAM copolymers at high temperature and the thermal-properties of polymethacrylimide（PMI） were investigated. The results show that the cycle-reaction temperature of MAN-MAA-MAM copolymer is 160℃ and PMI is stable at 280℃ in air. |
