Problems solved by technology

[0003] At present, the polymer substrate materials are mainly polyethylene terephthalate (PET) and polyimide (PI) resin, but the thermal stability of PET is poor, and it is easy to shrink under high temperature conditions.
On the other hand, although the thermal stability of polyimide is better, its solubility is poor

Embodiment 1

[0051] This embodiment provides a transparent polyamide-imide resin, which has the following repeating structural units, and the transparent polyamide-imide resin is named PAI-DFP-1.

[0052]

[0053] n is a repeating structural unit, and is 1000-5000.

[0054] A kind of preparation method of transparent polyamide-imide resin PAI-DFP-1 is as follows:

[0055] (1) The synthesis of diacid monomer (ODPA-ABA), this reaction can be represented by following reaction formula:

[0056]

[0057] In a 100ml three-necked flask, add 4,4'-oxydiphthalic anhydride (ODPA) (6.2g, 0.02mol), 4-aminobutyric acid (ABA) (4.68g, 0.04mol) and 40ml acetic acid, under nitrogen Under the atmosphere, the temperature was slowly raised to 110°C, and the reaction was carried out for 11 hours. The reaction solution was cooled to room temperature, filtered to obtain white diacid monomer (ODPA-ABA) (6.95 g, 0.0164 mol), yield: 82%.
