Examples
Embodiment 1
[0038] Add 200g of norbornene diacid anhydride into 500ml of glacial acetic acid, stir and dissolve evenly, raise the temperature to 120°C, slowly add 100g of 4,4'-diaminodiphenyl ether while stirring, condense and heat under reflux for 12h. Deionized water was added to the reaction solution to precipitate a white precipitate, which was filtered by suction and dried in vacuo to obtain 280 g of a crosslinking agent intermediate 4,4'-bis(norbornene-5,6-diamidyl)-p-phenylene ether white powder, Yield 95%.
[0039] Add 200g of lithium aluminum tetrahydride to 200ml of ether, stir and mix well. Take 200g of 4,4'-bis(norbornene-5,6-diamido)-p-phenylene ether and dissolve it in 200ml of dichloromethane, and slowly add it dropwise to the ether solution of lithium aluminum hydride mentioned above at 0°C, at room temperature Under reaction 24h. The reaction solution was suction filtered to obtain a colorless solution, added anhydrous magnesium sulfate to dry, suction filtered, and rot...
Embodiment 2
[0041] Add 250g of norbornene diacid anhydride to 500ml of glacial acetic acid, stir and dissolve evenly, raise the temperature to 120°C, slowly add 100g of 4,4'-diaminodiphenyl ether while stirring, condense and heat under reflux for 12h. Deionized water was added to the reaction solution to precipitate a white precipitate, which was filtered by suction and dried in vacuo to obtain 350 g of a crosslinking agent intermediate 4,4'-bis(norbornene-5,6-diamidyl)-p-phenylene ether white powder, Yield 93%.
[0042]Add 200g of lithium aluminum tetrahydride to 200ml of ether, stir and mix well. Take 200g of 4,4'-bis(norbornene-5,6-diamido)-p-phenylene ether and dissolve it in 200ml of dichloromethane, and slowly add it dropwise to the ether solution of lithium aluminum hydride mentioned above at 0°C, at room temperature Under reaction 24h. The reaction solution was filtered with suction to obtain a colorless solution, dried by adding anhydrous magnesium sulfate, filtered with suctio...
Embodiment 3
[0044] Add 300g of norbornene diacid anhydride to 500ml of glacial acetic acid, stir and dissolve evenly, raise the temperature to 120°C, slowly add 100g of 4,4'-diaminodiphenyl ether while stirring, condense and heat under reflux for 12h. Deionized water was added to the reaction solution to precipitate a white precipitate, which was filtered by suction and dried in vacuo to obtain 400 g of a crosslinking agent intermediate 4,4'-bis(norbornene-5,6-diamidyl)-p-phenylene ether white powder, Yield 88%.
[0045] Add 200g of lithium aluminum tetrahydride to 200ml of ether, stir and mix well. Take 250g of 4,4'-bis(norbornene-5,6-diamido)-p-phenylene ether and dissolve it in 200ml of dichloromethane, and slowly add it dropwise to the ether solution of lithium aluminum hydride mentioned above at 0°C, at room temperature Under reaction 24h. The reaction solution was filtered with suction to obtain a colorless solution, dried by adding anhydrous magnesium sulfate, filtered with sucti...
