一种含酚羟基半脂环聚酰亚胺及其制备方法与应用
摘要：
本发明属于化学合成领域，具体涉及一种含酚羟基半脂环聚酰亚胺及其制备方法与应用。所述的含酚羟基半脂环聚酰亚胺，具有式Ⅰ所示结构；其制备方法，包含如下步骤：N2保护下，将2,2＇-双(3-氨基-4-羟基苯基)丙烷溶于强极性非质子有机溶剂中，然后加入1,2,4,5-环己烷四甲酸二酐，搅拌0.5～3h后，加入共沸脱水剂和催化剂，升温到180～200℃，回流3～5h；将回流后的混合液冷却，用沉析剂沉析混合液中的固体产物，然后将固体产物过滤，洗涤，干燥，得含酚羟基半脂环聚酰亚胺。本发明还提供了一种聚酰亚胺薄膜，该膜由上述含酚羟基半脂环聚酰亚胺制备得到。
摘要（英）：

The invention belongs to the field of chemical synthesis, and particularly relates to semi-alicyclic polyimide containing phenolic hydroxyl groups and a preparation method and an application thereof. The semi-alicyclic polyimide containing phenolic hydroxyl groups has a structure as shown in formula I shown in the description. The preparation method comprises the following steps: dissolving 2,2'-bis(3-amino-4-hydroxyphenyl) propane in a strong polar aprotic organic solvent under N2 protection, then adding 1,2,4,5-cyclohexane tetracarboxylic dianhydride, stirring for 0.5-3 h, adding an azeotropic dehydrating agent and a catalyst, heating to 180-200 DEG C, and performing reflux for 3-5 h; cooling mixed liquid after reflux, using a preciptant to precipitate a solid product in the mixed liquid, and then filtering, washing and drying the solid product to obtain the semi-alicyclic polyimide containing the phenolic hydroxyl groups. The invention further provides a polyimide film, and the film is prepared from the semi-alicyclic polyimide containing the phenolic hydroxyl groups.
