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。
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.
