【摘要】 以甲基丙烯酸、甲基丙烯腈和甲基丙烯酰胺为主要单体原料,在适当的发泡剂存在下,以过氧化物为引发剂引发单体共聚,制得甲基丙烯酸-甲基丙烯腈-甲基丙烯酰胺共聚物,并在高温下进行发泡和环化反应,制得聚甲基丙烯酰亚胺(PMI)泡沫,并表征了PMI泡沫的结构。更多还原

【Abstract】 Methacrylic acid-methacrylonitrile-methacrylamide copolymer containing blowing agent were synthesized by using methacrlic acid,methacrylonitrile and methacrylamide as main raw materials,and peroxide as initiator,and then the polymethacrylimide foams were prepared via foaming these copolymer at high temperature and characterized.更多还原
