The present invention provides a bis-(hydroxyphthalimide) prepared by reacting 4-hydroxyphthalic anhydride and an organic diamine in the presence of an organic solvent under heating. The bis(hydroxyphthalimide) has two intramolecular imide rings and active hydrogens, and is thus polymerizably to form a variety of polycondensation products each having imide rings by condensation. The bis-(hydmxyphthalimide) is also reacted with a dicarboxylic acid dihalide to form a polyesterimide, through condensation, which is excellent in transparency and heat resisting property.
本发明提供了一种双(羟基邻苯二甲酰亚胺),其制备方法是在有机溶剂存在下,加热使 4-羟基邻苯二甲酸酐和有机二胺发生反应。双(羟基邻苯二甲酰亚胺)具有两个分子内亚胺环和活性氢,因此可通过缩合形成各种具有亚胺环的缩聚产物。双(羟基邻苯二甲酰亚胺)还可与二羧酸二卤化物反应,通过缩合形成聚酯酰亚胺,该聚酯酰亚胺具有优异的透明度和耐热性能。
