Embodiment 1
[0045] Example 1 Preparation of PFBEK
[0046] Under the protection of nitrogen atmosphere, in a three-necked flask equipped with mechanical stirring, was added the furan ring structure bio-based monomer BFBF (10mmol, 3.1227g), 9,9-bis (4-hydroxyphenyl) fluorene BPF (10mmol, 3.5042g) and anhydrous potassium carbonate K 2 CO 3 (14mmol, 1.9023g) was dissolved in a mixed solvent of 4ml sulfolane, 1ml N-methylpyrrolidone and 10ml toluene, reacted at 125℃~160℃ for 4h, evaporated toluene in the mixed system, and then heated to 195℃ and reacted for 10h. The viscous solution was poured into hot water to obtain a white fibrous polymer, which was boiled in boiling water for 8-12 hours and then dried to constant weight to obtain a white crude product of PFBEK containing furan ring structure bio-based polyaryl ether ketone resin. The crude product was dissolved in chloroform in a certain proportion, then filtered, filtered overnight and settled in absolute ethanol, and then filtered, air-dri...
Embodiment 2
[0049] Example 2 Preparation of polymer PFDEK
[0050] Under the protection of nitrogen atmosphere, in a three-necked flask equipped with mechanical stirring was added the furan ring structure bio-based monomer BFBF (10mmol, 3.1227g), phthalazinone biphenyl DHPZ (10mmol, 2.3824g) and anhydrous Potassium Carbonate K 2 CO 3 (14mmol, 1.9023g) dissolved in a mixed solvent of 3ml sulfolane, 2ml N,N-dimethylacetamide and 10ml toluene, react at 125℃~160℃ for 4h, distill off the toluene in the mixed system, and then heat up to 195℃ React for 10 hours, and finally pour the viscous solution into hot water to obtain a white fibrous polymer, boil it in boiling water for 8-12 hours, and then dry to constant weight to obtain a white bio-based polyaryl ether ketone containing furan ring structure Crude resin PFDEK. The crude product was dissolved in chloroform according to a certain proportion, and then filtered, the filter was settled overnight in absolute ethanol, and then filtered, air-drie...
