摘要 合成了三种AB型聚酰亚胺单体:4-(4-氨基苯氧基)邻苯二甲酸(单体4),4-(3-氨基苯氧基)邻苯二甲酸(单体7)和对(间)乙基4-(3-氨基苯氧基)邻苯二甲酸酯(单体8或9)。利用热失重分析(TGA)对比研究了这三种AB型聚酰亚胺单体的热行为。结果表明,单体4、单体7和单体8(9)在升温的过程中能发生热聚合生成聚酰亚胺。将单体4用于气相沉积聚合设备,得到了均匀透明的聚酰亚胺薄膜。对分子结构的修饰使单体8(9)较之单体7有更好的挥发性。 This article has synthesizes three types of AB-type polyimide monomers：4 - （4-aminophenoxyl） phthalic acid （monomer 4） ,4 - （3-aminophenoxyl）phthalic acid （ monomer 7 ） and p - and m - monoethyl 4 - （3- aminophenoxyl） phthalate（ monomer 8/9）. Thermogravimetric analysis is used for a comparison study of the thermal behavior of monomer 4, monomer 7 and monomer 8 （ 9 ）. As a result of thermal analysis of monomers, it is indicated that monomer 8 （9）, which exhibits high volatility, can be thermally polymerized to polyimide at elevated temperature. Transparent polyimide film with good uniformity is obtained by vapor deposition polymerization from monomer 4.
