Synthetic example (A
[0372] In a three-necked flask, 18.31 g (0.05 mol) of BAHF, 17.42 g (0.3 mol) of propylene oxide, and 100 mL of acetone were weighed and dissolved. A solution obtained by dissolving 20.41 g (0.11 mol) of 3-nitrobenzoyl chloride in 10 mL of acetone was added dropwise thereto. After completion|finish of dripping, it made it react at -15 degreeC for 4 hours, and returned to room temperature after that. The precipitated white solid was taken out by filtration and vacuum-dried at 50°C. 30 g of the obtained solid was put into a 300 mL stainless steel autoclave, dispersed in 250 mL of 2-methoxyethanol, and 2 g of 5% palladium-carbon was added. Hydrogen was introduced thereinto with a balloon, and it was allowed to react at room temperature for 2 hours. After 2 hours, confirm that the balloon does not continue to deflate. After completion of the reaction, the palladium compound as a catalyst was removed by filtration, and concentrated by distillation under reduced pressure to obtai...

[0375] The synthesis of synthetic example 1 polyimide (PI-1)
[0376] Under the flow of dry nitrogen, weigh 31.13g (0.085mol; 77.3mol% relative to the structural units from all amines and derivatives thereof) of BAHF, 1.24g (0.0050mol; relative to the structural units from all amines and 4.5 mol% of the structural units of amines and their derivatives) of SiDA, 2.18g (0.020 mol; 18.2 mol% relative to the structural units of all amines and their derivatives) of MAP as an end-capping agent, 150.00 g of NMP and allowed to dissolve. A solution obtained by dissolving 31.02 g (0.10 mol; 100 mol % relative to structural units derived from carboxylic acids and derivatives thereof) of ODPA dissolved in 50.00 g of NMP was added thereto, stirred at 20° C. for 1 hour, and then Stir at 50°C for 4 hours. Then, 15 g of xylene was added, and stirring was carried out at 150° C. for 5 hours while azeotroping water and xylene. After the reaction was completed, the reaction solution was poured...
