Synthetic example 1
[0086] A reflux condenser with a stainless steel anchor stirrer, a nitrogen inlet pipe, and a collector with a closed-circuit cock with a spherical condenser is installed in a three-necked separable (Separable) flask with a capacity of 2 liters. The following reactions were carried out in a gas stream.
[0087] Dissolve 58.46g (200mmol) of 1,3-bis(3-aminophenoxy)benzene (hereinafter APB) in 400g of γ-butyrolactone, and add 64.4g (200mmol) of benzophenone tetra Carboxylic dianhydride was reacted at room temperature for 2 hours. Then 3.0 g (30 mmol) of γ-valerolactone, 4.1 g (46 mmol) of pyridine, 344 g of γ-butyrolactone, and 100 g of toluene were added. The reaction was carried out at 180° C. (bath temperature) for 3 hours while blowing nitrogen gas, while removing the azeotrope of toluene and water, to obtain a solvent-soluble polyimide varnish 1 .
Synthetic example 2
[0089] The following reactions were carried out in the same vessel as above. Add 44.9g (200mmol) bicyclo (2,2,2) oct-7-ene-2,3,5,6-tetracarboxylic dianhydride (below BTA), 15.2g (100mmol) 3,5-diamino Benzoic acid (hereinafter DABZ), 3.0g (30mmol) γ-valerolactone, 4.1g (46mmol) pyridine, 172g γ-butyrolactone, 60g toluene. The reaction was carried out at 180° C. (bath temperature) for 1 hour while blowing nitrogen gas. The azeotrope of toluene and water was removed. Add 29.4g (100mmol) 3 in this reaction solution, 4,3 ', 4'-diphenyltetracarboxylic dianhydride (hereinafter BPDA), 58.46g (200mmol) APB, 172g gamma-butyrolactone, 40g toluene, side The reaction was carried out at room temperature for 1 hour while blowing nitrogen gas. Then, removing the azeotrope of toluene and water, it was made to react at 180 degreeC (bath temperature) for 3 hours, and the solvent-soluble polyimide varnish 2 was obtained.
Synthetic example 3
[0091] The following reactions were carried out in the same vessel as above. 44.9 g (200 mmol) of BTA, 20.0 g (100 mmol) of 3,4-diaminodiphenyl ether, 3.0 g (30 mmol) of γ-valerolactone, 4.1 g (46 mmol) of pyridine, 172 g of γ-butyrolactone, and 60 g of toluene were added. The reaction was carried out at 180° C. (bath temperature) for 1 hour while blowing nitrogen gas. The azeotrope of toluene and water was removed. 29.4 g (100 mmol) of BPDA, 58.46 g (200 mmol) of APB, 172 g of γ-butyrolactone, and 40 g of toluene were added to the reaction liquid, and the mixture was reacted at room temperature for 1 hour while blowing nitrogen gas. Then, removing the azeotrope of toluene and water, it was made to react at 180 degreeC (bath temperature) for 3 hours, and the solvent-soluble polyimide varnish 3 was obtained.
