Embodiment 1
[0096] Add 1,3-bis(3-aminophenoxy)benzene 12.00 g, 1,3-bis(3-maleimidephenoxy)benzene 15.94 g and 48.70 g of N,N-dimethylacetamide was stirred at 50° C. for 1 hour under a nitrogen atmosphere. Then the system was lowered to room temperature, while paying attention to the rise of the solution temperature, 11.90 g of 3,3',4,4'-benzophenone tetracarboxylic dianhydride was added in batches, and then the temperature was raised to 50° C. and stirred for 4 Hour.
[0097] A portion of the polyamic acid solution containing the obtained bismaleimide compound was taken out, cast on a glass plate, and then heated from 50° C. to 270° C. at a rate of 7° C. / min to obtain a film with a thickness of 20 μm. The glass transition temperature (Tg) of the obtained polyimide film was 106°C.
[0098] Separately, a part of the polyamic acid solution containing the obtained bismaleimide compound was cast on a copper foil (manufactured by Nippon Denya Co., Ltd., SLP-35, thickness 35 μm), and the tempe...

[0102] The polymerization, compounding and evaluation were carried out in the same manner as in Example 1 except that the type and compounding amount of the diamine compound or bismaleimide compound were changed. Table 1 shows the results. The 1,3-bis(3-(3-aminophenoxy)phenoxy)benzene and 1,3-bis(3-(3-(3-aminophenoxy)phenoxy)benzene used at this time oxy)benzene and 1,3-bis(3-(3-maleimidephenoxy)phenoxy)benzene use 1 Identification by H-NMR and FD-mass spectrometry.
[0103] 1,3-bis(3-(3-aminophenoxy)phenoxy)benzene: 1 H-NMR (CD 3 SOCD 3 )δ: 5.24(s, 4H), 6.12-6.16(ddd, 2H, J=7.83, 2.43, 0.82Hz), 6.23(t, 2H, J=2.30Hz), 6.33-6.37(ddd, 2H, J= 7.83, 2.43, 0.82Hz), 6.61(t, 2H, J=2.43Hz), 6.67(t, 1H, J=2.43Hz), 6.71-6.80(m, 6H), 6.99(t, 2H, J=7.83 Hz), 7.35(t, 2H, J=7.83Hz), 7.38(t, 1H, J=7.83Hz) FD-mass spectrum 476(M+) 1,3-bis(3-(3-(3-aminophenoxy Base) phenoxy) phenoxy) benzene: 1 H-NMR (CD 3 SOCD 3)δ: 5.21(s, 4H), 6.11-6.12(ddd, 2H, J=7.83, 2.16, 0.81Hz), 6.21(t, 8H, J=...
Embodiment 5
[0106] Add 855 g of N,N-dimethylacetamide as a solvent to a container equipped with a stirrer and a nitrogen gas introduction tube, add 69.16 g of 1,3-bis(3-aminophenoxy)benzene therein, and dissolve at room temperature and stir. Then, 75.84 g of 3,3',4,4'-benzophenone tetracarboxylic dianhydride was added, and stirred at 60°C to obtain a polyamic acid solution. The content of polyamic acid was 15% by weight. 48.3 g of 1, 3- bis (3-maleimide phenoxy) benzene was added to 500 g of some obtained varnishes, and it stirred at room temperature for 2 hours.
[0107] Using a commercially available polyimide resin film (manufactured by Toray Dupon Co., Ltd., trade name: Capton (registered trademark) 150EN), the obtained bismaleimide compound-containing polyamic acid solution was prepared by the aforementioned method. Part of it is coated with a rubber roller so that the thickness after drying is 2 μm, and dried in an air cushion drying oven at 115°C for 2 minutes, at 150°C for 2 min...
