| 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。

| Abstract: | 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. |
